p9036b product datasheet revision 1.0.0 13 ? 2016 integrated device technology, inc . theory of operation the p9036b is a highly - integrated wpc 1 (wireless power consortium) - compliant wireless power char ging ic solution for the transmitter b ase station. it can deliver 5w in wpc qi mode using near - field magnetic induction as a m eans to transfer energy o verview figure 1 shows t he block diagram of the p9036b . when the vin_uvlo block detects that the voltage at reg_in and buck5vt_in ( connected together externally) is above the vin_rising uvlo threshold and en is at a logic low, the enable sequence circuitry activates the voltage reference, the 5v and 2.5v ldo s , and the 5v buck switching regulator . the voltages at the outputs of the ldos and the buck regulator are monitored to ensure that they remain in regulation , and the adapto r voltage, coil current, and internal temperature are monitored . t he digital block and the mcu drive an internal half bridge inverter. this inverter powers the transmitter (tx) coil through the sw pins. the tx and reci ever (rx) act as a loosely coupled, air core transformer. the tx coil generates a magnetic field that supplies energy to the rx coil the rx uses that field to generate a dc output voltage that is applied to the load. communication packets from the receiver in the mobile device are detected and filtered by an external operational amplifier and passive filter, then provided to the hpf pin to be further processed by the demodulator and converted to digital signals that can be read by the mcu. several interna l voltages are digitized by the adc and supplied to the mcu for system control and algorithm C related purposes . two gpio ports are available to the system designer for driving leds and a buzzer. the clock for the mcu and other circuitry is generated by an internal rc oscillator. i 2 c sda and scl pins permit communication with an external device or host. note 1 - refer to the wpc specification at http://www.wirelesspowerconsortium.com/ for the mos t current information under voltage lockout (uvlo) the p9036b has a built - in uvlo circuit that monitors the input voltage and enables normal operation, as shown in the following figure: time ( 1 s / div ) v coil ( 10 v / div ) uvlo exit event v in ( 5 v / div ) v in = 10 v 0 v 0 v . over - temperature protection the internal temperature of the p9036b is monitored. t he part shut s down if the temperatu re exceeds 140c (typ) and reactivates when the temperature falls below 1 1 0c (typ) . in ternal driver s and inverter the internal gate d river circuitry drives the transmitter coil which delivers energy to the reciever (rx) coil . the internal fets are configured as a power inverter that switches the top sides of the resonant circuits between the vin supply voltage and ground at a rate set by the mcu control algorithm . demodulator power is transferred from the transmitter to the receiver through the coupling of their respective coils: a loosely - coupled transformer. the amount of power transferred is determined by the transmitters switching frequency

( 110 khz - 205khz , by wpc 1 ), and is controlled by the receiver through instructions the receiver sends back through the same coils to the transmitter to increase or decrease power , end power transfer, or another wpc command . the instructions take the form of data packets which the receiver modulates on the carrier. the modulation is detected and then coupled through a series of filters connected to the p9036b s demodulator and th en fed to the hpf pin. recovering the data packets is the function of the demodulator. decoding and executing the packets is one of the functions of the mcu. micro controller unit (mcu) the p9036b s mcu processes the algorith m, commands, and data that cont rol the p ower transferred to the rec ei ver. the mcu is provided with ram and rom, and parametric trim and operational modes are set at the factory through the one - time programming (otp) block , read by the mcu at power - up . communication with external m emory is performed through i 2 c via the scl and sda pins. applications information the recommended applications schema t ic diagram is shown in figure 7. the p9036b operates from a 12 v dc (5% ) input . the switchin g frequency varies from 110 khz to 205khz. the power transfer is controlled via change s in switching frequency. the b ase or tx - side has three series - resonance circuit s made of a wpc type - a6 triple coil and three capacitors . the resonant circuits are driven by a n internal half - bridge inverter , as shown in figure 5 . only the resonant circuit that is aligned with the receiver coil is activated . the selection is m ade by voltage levels from gpio0, gpio2 a nd gpio6, each of which drives one of three external selection fet s directly which activates the respective coil . internal mosfet driver 12 v + - gpio 0 gpio 2 gpio 6 a 6 coil figure 5 half bridge i nverter tx coil driver. external chip reset and en t he p9036b can be externally reset by pulling the reset pin to a logic high above the v ih level. th e reset pin is a dedicated high - impedance active - high digital input , and its effect is similar to the power - up reset functi on. because of the internal low - voltage monitoring scheme, the use of the external reset pin is not mandatory. a manual external reset scheme can be added by connecting 5v to the reset pin through a simple switch . when reset is high , the microcontrollers registers are set to the default configu ration. when the reset pin is released to a low, the micr ocontroller starts executing the code from the eeprom . if the particular application requires the p9036b to be disabled, this ca n be accomplished with the en pin. when the en pin is pulled high, the device is suspended and placed in low current (sleep) mode. if pulled low, the device is active. the current into en is approximately ? ?? ? ? ? ? = ? ?? ? ? ? ? ? ? 2 ? 300 ? for input voltages between v in and +2v , and close to zero if v( en ) is less than 2v. system feedback control (wpc) the p9036b contains logic to demodulate and decode error packets sent by the mobile device (rx - side) , and adjusts power transfer accordingly. the p9036b varies the switchin g frequency of the in ternal half bridge inverter between 11 0 khz to 205 khz to adjust power transfer. the mobile device controls the amount of power transfer red via a communication link that exists from the mobile device to the base station. the mobile device ( any wpc - compliant receiver ) communicates with the p9036b via communication p ackets. each packet has the following format: table 6 C data packet format. preamble header message checksum the overall system behavior between the transmitter and receiver follows the state machine diagram below:
p9036b product datasheet revision 1.0.0 15 ? 2016 integrated device technology, inc . figure 6 system state machine d iagram the p9036b performs four phases: selection, ping, identification & configuration, and power transfer. start (selection) phase in this phase, the p9036b operates in a low power mode to determine if a potential receiver has been placed on the coil surface prior to the ping state. at regular intervals, t he p9036b applies a brief ac signal sequentially to each one of the coils of the triple a6 coil and liste ns for a response. when a response is found, the p9036b keeps that coil selected for all subsequent operations . ping phase in this phase, the p9036b applies a power signal at 175 khz with a fixed 50% duty cycle and attempts to establish a communicati on li nk with a m obile device. required packet(s) in ping : 1. signal strength p acket (0x01) the m obile device must send a signal strength packet within a time period specified by the wpc , otherwise the power signal is terminat ed and the process repeats. if the p9036b does not detect the start bit of the header byte of the signal strength p acket during the ping phase , it removes the power s ignal after a delay . if a signal strength p acket is received, the p9036b goes to the identifi cation and configuration phase. identification and configuration (id & config) in this phase, the p9036b tries to identify the mobile device and collects configuration information. required packet(s) in id & config : 1. identification p acket (0x71) 2. extended identification p acket (0x81) * 3. configuration p acket (0x51) * if ext bit of 0x71 packet is set to 1. also, the p9036b must correctly receive the following sequence of packets without changing the operating point (175 khz @ 50% duty cycle): 1. identification packet (0x71) 2. extented identification (0x81) 3. u p to 7 optional configuration p ackets from the following set: power control hold - off packet (0x06) , proprietary packet (0x18 C 0xf2) , reserved packet 4. configuration packet (0x51) if the p9036b detect s a valid configuration sequence, with the proper timing, then it will move to the power transfer phase. otherwise, it will terminate the power signal and revert to the selection phase. power transfer phase in this phase, the p9036b adapts the power transfer to the receiver based on contro l data it receives as contained in the c ont rol error p ackets. required packet(s) in power transfer : 1. control error packet (0x03) 2. rectified power packet (0x04) for this purpose, the p9036b may receive zero or more of the following p ackets: 1. control error packet (0x03) 2. rectified power packet (0x04) 3. charge status packet (0x05) 4. end power transfer packet (0x02) 5. any proprietary packet 6. any reserved packets if the p9036b receives a p acket that does not comply with the sequence, or if the time limits for receiving the
p9036b product datasheet revision 1.0.0 16 ? 2016 integrated device technology, inc . expected packets are exceeded, then p9036b will terminate the power signal and revert to the selection phase. external over temperature protection at all times the p9036b periodically checks the dc voltage from the external thermistor circuit. if the external temperature limit is exceeded, then the p9036b immediately terminates the power transfer and signals an error condition on the led outputs. it remains in this state until the over temperature condition is corrected. foreign object detection (fod) the p9036b supports foreign object detection in accordance with wpc specifications. periodically the receiver reports to the p9036b the amount of recei ved power by sending a received power packet. the p9036b compares the amount of power transmitted with the report amount of received power. if too much power is being lost then the presence of a foreign object is assumed. in that case, the p9036b terminate s the power transfer and signals an error condition on the led outputs. the calibration of the fod is primarily set in the p9036b firmware. however, some adjustment of the fod is possible by changing external resistor values that change the dc voltage seen by gpio4.there are three cases for 1. pull down resistor only is no adjustment to the internal firmwares fod setting. 2. pull up resistor only disables the fod function 3. a combination of pullup/pulldown resistors creates a dc voltage which determines an amoun t of offset that will be added or subtracted from the internal firmware settings. if the dc voltage is approximately 1.20v then the adjustment will be zero. if the voltage is greater than 1.2v then the adjustment will increase the allowance for foreign obj ects up to approximately 300mw additional loss. if the voltage is less than 1.2v then the adjustment will decrease the allowance for foreign objects up to approximately 300mw less loss. this adjustment is proportional throughout a voltage range between app roximately 50mv to 2.35v

revision 1.0.0 19 ? 2016 integrated device technology, inc p9036b product datasheet external components the p9036b requires a minimum number of external components for proper operation (see the bom in table 7). a complete design schematic compliant to the wpc qi standard is given in figure 7 . it includes wpc qi led signaling, buzzer, and an eeprom for loading p9036b firmware. i 2 c communication the p9036b includes an i2c block which can support either i2c master or i2c slave operation. after power - on - reset (por),the p9036b will initially acts as an i2c master for the purpose of downloading firmware from an external memory device, such as an eeprom. the i2c master mode on the p9036b does not support multi - master mode, and it is important for system designers to avoid any bus master conflict until the p9036b has finished any firmware uploading and has released control of the bus as i2c master. after firmware downloaded from external memory is complete, and when the p9036b begins normal operation, the p9036b is configur ed by the standard firmware to be exclusively in i2c slave mode. eeprom the p 9036b evk supports an external eeprom memory chip,pre - programmed with a standard operating firmware that is automatically loaded when 5v power is applied. the p 9036b uses i2c mas ter address 0x52 to access the eeprom. the p 9036b slave address is 0x39. if the standard firmware is not suitable for the application, a custom eeprom or internal factory programmed rom is possible. for future flexibility, the p9036b will first sequentiall y try to communicate with the eeprom first using address 0x50, then 0x52, and finally 0x54. each address supports a different formatting of the eeprom data. at this time, the only supported format is at address 0x52. when the p9036b receives a response fro m the eeprom, the sequencing will stop and the p9036b will use the firmware that is up loaded from that address. overview of standard gpio usage th ere are 7 gpios on the p9036b transmitter ic, of which two are available for use as follows: ? gpio0,2,6: selects one of the three available coils. ? gpio1,5: manages the demodulation signal selection. ? gpio3: green led and external resistors for choosing led mode. ? gpio4: red led and ac or dc buzzer (o ptional) and external resistors for choosing fod offset option . table 8 table lists how the red and green leds can be used to display information about the p9036b s operating modes. the table also includes information about external resistors or internal pull up/down options to select led modes. led functions two gpios are used to drive leds, which indicate, through various on/off and illumination options, the state of charging and some possible fault condit ions. as shown in figure 8 , one or two resistors configure the defined led option combinations. the dc voltage set in this way is read one time dur ing power - on to determine the led configuration. idtp 9036 to adc ra rb ldo 2 p 5 v _ out gpio 3 resistor to set options led mode resistor configuration figure 8 p9036b led resistor options .

revision 1.0.0 21 ? 2016 integrated device technology, inc p9036b product datasheet range must be used at the vin input s (in,in1,in2) to minimize ripple current and voltage droop due to the large current requirements of the resonant half half - bridge driver . t he value of the capacitors will decrease as the voltage applied approaches the nominal voltage, due to the ceramic dielectric characteristics . for example, a 22 f x7r 25v capacitors value could be as low as 6f when operating at 13 v , depending on the manufacturer . wpc tx - a6 coil the internal half - bridge output connect s to three series - resonance circuit s made by a wpc triple type - a6 coil and s eries resonant capacitor s. the selected induct or serves as the primary coil of a loosely - coupled transformer, the secondary of which is the inductor co nnected to the power receiver. resonance capacitors the resonance capacitors must be c0 g type diele ctric an d have a dc rating of at least 10 0v. the pa rt numbers are shown in the bill o f materials buck converter the input capacitors (c in ) must be connected directly between the power pins (reg_in and buck5vt_in) and power p gnd pins as near as possible to the ic pins . the output capacitor (c out ) must be placed as close to the device and power ground pins (pgnd) as possible. the output - sense connection to the feedback pin, buck5vt_sns, must be separ ated from any power trace. connect the output - sense trace as close as possible to the load point to avoid additional load regulation errors . the power traces, including p gnd traces, the lx or 5v output traces , and the vin trace must be kept short, direct and wide to allow large current fl ow. use several via pads when routing power lines between layers . ldo s input capacitor the input capacitors must be located as physically close as possible to the power pin ( ldo2p5v_in ) and power ground ( gnd). ceramic capacitors are recommended for their l ow esr and small profile. typically, 10v - or 16v - rated capacitors are recommended . output capacitor for proper vo ltage regulation and stability, a capacitor is req uired on the output of each ldo ( ldo2p5v and ldo5v) . the output capacitor must be placed as close to the device and power (pgnd) pins as possible. since the ldo s have been designed to function with very low esr capacitors, a ceramic capacitor is reuqired for best performance. pcb layout considerations - for optimum device performance and l owest output phase noise, the following guidelines must be observed. please contac t idt for g erber files that contain the recommended board layout. - as for all switching power supplies, especially those providing high current and using high switching fre quencies, layout is an important design step. if layout is not carefully done, the regulator could show instability as well as emi problems. therefore, use wide and short traces for high current paths. if there are any uncertainties regarding best layout p ractices it is best to follow the provided, optimized idt layout. - the 0. 1f decoupling capacitors must be mounted on the component side of the board as close as possible to the pin s intended to be decoupled . keep pcb trace s to each power pin and to ground via s as short as possible . - to optimize board layout , place all components on the same side of the board . - all passive components in the network connecting to the hpf pin, up to and including the three small signal diodes must be placed close to the hpf pi n. this is a high sensitivity analog circuit, and traces with high voltage or high noise must be routed away from this area. it is especially important to mount the capacitor connecting to the hpf pin as close as possible to the hpf pin. additionally, the hpf pin is a high impedance input and any dc leakage into this node can reduce performance.
p9036b product datasheet revision 1.0.0 22 ? 2016 integrated device technology, inc. - the nqg48 6 .0 mm x 6.0 mm x 0. 75 mm 48l package has an inner thermal pad, which requires blind assembly. it is recommended that a more active flux solder paste be u sed such as alpha om - 350 solder paste from cookson electronics ( http://www.cooksonsemi.com ). please contact idt for g erber files that contain recommended solder stencil design. - the package center e xposed p ad (ep) must be reliably soldered directly to the pcb. the center land pad on the pcb must also be tied to the board ground plane , primarily to maximize thermal performance in the application. the g round connection is best achi e ved using a matrix of plated - throu gh - hole (pth) vias embedded in the pcb center land pad for the ntg48. the pth vias perform as thermal conduits to the ground plane (thermally, a heat spreader) from the solder side of the board. - on the solder side of the board , these thermal vias embed in a copper fill having the same dimensions as the center land pad on the component side. recommendations for the via finished hole - size and array pi tc h are 0.3mm to 0.33mm and 1.3mm, respectively. power dissipation/thermal requ irements the p9036b is offered in a tqfn - 48l package . the m aximum pow er dissipation capability is 1.3w , limited by the dies specified maximum operating junction temperature, t j , of 125 c . the junction temperature rise s with the device power dissipation based on the package thermal resistance. the package offers a typical thermal resistance, junction to ambient ( ja ), of 31 c/w when the pcb layout and surrounding devices are optimized as described in the pcb layout considerations section. the techniques as noted in the pcb layout section need to be followed when designing th e printed circuit board layout. care should be exercised to avoid the placement of the p9036b ic package in proximity to other heat generating devices in a g iven application design. the ambient temperature around the power ic will also have an effect on the thermal limits of an application. t he overall goal is to have as much uninterrupted copper material on both the top and bottom layers of the pcb to carry away heat away for the p9036b as quickly as possible. special notes nqg tqfn - 48 package assembly note 1: unopened dry packaged parts have a one year shelf life. note 2: the hic indicator card for newly opened dry packaged parts should be checked . if there is any moisture content, the parts must be baked for a minimum of 8 hours at 125?c within 24 hours of the assembly reflow process.
