| HIP0045 Data Sheet April 1999 File Number 4047.2 1A/50V Octal Low Side Power Driver With Serial Bus Control and Fault Protection The HIP0045 is a logic controlled, eight channel Octal Serial Power Low Side Driver. The serial peripheral interface (SPI) utilized by the HIP0045 is a serial synchronous bus compatible with Intersil CDP68HC05, or equivalent, microcomputers. As shown in the Block Diagram for the HIP0045, each of the open drain MOS Output Drivers have individual protection for overvoltage and over-current. Each output channel has separate output latch control with fault unlatch and diagnostic or status feedback. Under normal ON conditions, each output driver is in a low voltage, high current state of saturated turn-on. Comparators in the diagnostic circuitry monitor the output drivers to determine if an out of saturation condition exists. If a fault is sensed, the respective output driver for Channels 0 - 5 have overcurrent latch-off. Channels 6 and 7 are configured for lamp drivers and have current limiting with over-temperature latch-off. Channels 0 and 1 have direct parallel drive control for PWM applications and are ORed with the SPI Bus control. All channels are SPI Bus controlled and sense the output states for diagnostic feedback. The HIP0045 is fabricated in a Power BiMOS IC process, and is intended for use in automotive and other applications having a wide range of temperature and electrical stress conditions. It is particularly suited for driving relays, solenoids and lamps in applications where low standby power, high operating voltage, and high output current in high ambient temperature conditions is required. The HIP0045 is in a 20 lead plastic Power SOP (PSOP) Package with an integral copper `slug' to conduct heat directly to a PCB interface or heat sink on the bottom of the package.

BYTE TIMING DIAGRAM WITH ASYNCHRONOUS RESET Signal Pin Descriptions Power Output Drivers, OUT0 - OUT7 - The input and output bits corresponding to Output 0 thru Output 7 are transmitted and received most significant bit (MSB) first via the SPI bus. Outputs OUT0 - 5 are provided with overcurrent shutdown. Current Limiting and Thermal Shutdown are provided on OUT6, 7 for application use as Lamp Drivers. After a fault shutdown, the control lines remain active. The fault latches must be cleared by turning the output off and on to reset the output to an ON state. OUT1, 2 latches may be cleared by the RESET pin. RESET - Active low reset input. An internal pull-up is provided on-chip. When this input line is low, all output drivers are turned-off and the OUT1, 2 fault latches are cleared. An internal low voltage reset is ORed with the RESET input. When VCC is less than VLCC_RST, the internal reset is active. CE - Active low chip enable. The falling edge of CE loads the shift register with the output status bits. Data is transferred from the shift register to the outputs on the rising edge of CE. The output driver for the MISO pin is enabled when CE goes low. CE must be a logic low prior to the first serial clock (SCK) and must remain low until after the last (eighth) serial clock cycle. All eight MOSI bits of input data must be loaded in the same sequence of SCK clock input. A digital filter is used in the CE line to insure that 8 (or a multiple of 8) clock cycles occurs while CE is active low. After SCK is low for a short period, tLAG; CE may be changed from low to high to latch the input data. A low level on CE also activates an internal disable circuit used for unlatching output states that are in a fault mode as sensed by an out of saturation condition. A high on CE forces MISO to a high impedance state. Also, when CE is high, the octal driver ignores the SCK and MOSI signals. IN0, 1 - IN0 and IN1 are Channels 0 and 1 direct parallel input controls. Refer to `Special Input Conditions for Channel 0, 1` in the following text. SCK, MISO, MOSI - Refer to the `Serial Peripheral Interface' (SPI) section in the following text. Serial Peripheral Interface (SPI) The Serial Peripheral Interface (SPI) is a serial synchronous bus for control and data transfers. The Clock (SCK), which is generated by the microcomputer, is active only during data transfers. In systems using CDP68HC05 family microcomputers, the inactive clock polarity is determined by the CPOL bit in the microcomputer's control register. The CPOL bit is used in conjunction with the clock phase bit, CPHA to produce the desired clock data relationship between the microcomputer and octal driver. The CPHA bit in general selects the clock edge which captures data and allows it to change states. For the HIP0045, the CPOL bit must be set to a logic zero and the CPHA bit to a logic one. Configured in this manner, MISO (output) data will appear with every rising edge of the SCK clock pulse, and MOSI (input) data will be latched into the shift register with every falling edge of the SCK clock pulse. Also, the steady state value of the inactive serial clock, SCK, will be at a low level. Timing diagrams for the serial peripheral interface are shown in Figure 1. SPI Signal Descriptions MOSI (Master Out/Slave In) - Serial data input. Data bytes are shifted in at this pin, most significant bit (MSB) first. The data is passed directly to the shift register which in turn controls the latches and output drivers. MISO (Master In/Slave Out) - Serial data output. Data bytes are shifted out at this pin, most significant bit (MSB) first. This pin is the serial output from the shift register and is three stated when CE is high. Diagnostic Failure Register information is given in Tables 6 and 7. Determination of the fault condition may be done as a software sequence, based on MOSI data latched into the shift register and subsequent data clocked out of the MISO pin. 4-6 HIP0045 SCK - Serial clock input. The SCK signal clocks the shift register and new MOSI (input) data will be latched into the shift register on every falling edge of SCK. The SCK phase bit, CPHA=1 and the polarity bit, CPOL=0, must be set in the microcomputer's control register. SPI Shift Register The SPI shift register has both serial and parallel inputs and outputs. Serial output and input data are simultaneously transferred to and from the SPI bus. The serial input data is parallel latched into the 8-Bit Output Latch of the HIP0045 at the end of a data transfer. Diagnostic data, Diag0-7 is transferred to the shift register when CE goes low at the beginning of a data transfer cycle. Functional Descriptions The HIP0045 is a low quiescent power, high voltage, high current, octal, serial low side driver featuring eight channels of open drain MOS output drivers. Referring to the Detailed Block Diagram, the drivers have low rDSON and low saturation voltage with over-voltage drain-to-gate zener clamp circuits. Each output is short circuit protected and suited for driving resistive or inductive loads such as solenoids, relays and lamps. Data is transmitted to the device serially using the Serial Peripheral Interface (SPI) protocol. Each channel is independently controlled by an output latch and a common RESET line that disables all eight outputs. Byte timing with asynchronous reset is shown in Figure 2. 8-Bit Output Latch The 8-Bit Output Latch is used to control the output drivers. New serial data is transferred from the shift register to the 8-Bit Output Latch when CE goes high. The 8-Bit Output Latch is cleared by an active low RESET signal. Output Drivers The output drivers provide an active low output of 500mA nominal with current limiting set to greater than 1.05A to allow for high inrush currents. In addition, each output is provided with a voltage drain-to-gate clamp circuit to limit inductive transients. Each output driver is also monitored by a comparator for an out of saturation condition. If the output voltage of an ON output pin exceeds the saturation voltage limit, a fault latch turns off the output. The threshold comparators are used to detect shorts to the power supply, shorts to ground and open loads. Each comparator provides status data to the shift register for diagnostic feedback. An internal pull-down current, ISK at each output will provide an indicator for low output voltage if the output is programmed OFF and the output line is open. Refer to Tables 6 and 7 for Fault information versus output control and VREF. Note that VREF is the out-of-saturation threshold for an ON state. When the output is switched off and VREF is low, an openload or ground fault is indicated. CDP68HC05C4 MICROCOMPUTER PORT MOSI MISO SCK RESET CE HIP0045 MOSI MISO SCK RESET FIGURE 3. TYPICAL MICROCOMPUTER INTERFACE WITH THE HIP0045 The circuit receives 8-bit serial data by means of the serial input (MOSI), and stores this data in an internal register to control the output drivers. The serial output (MISO) provides 8-bit diagnostic data representing the voltage level at the driver output. This allows the microcomputer to diagnose the condition at the output drivers. The device is selected when the chip enable (CE) line is low. When (CE) is high, the device is deselected and the serial output (MISO) is placed in a threestate high impedance mode. The device shifts serial data on the rising edge of the serial clock (SCK), and latches data on the falling edge. On the rising edge of chip enable (CE), new input data from the shift register is latched to control the output drivers. The falling edge of chip enable (CE) transfers the output drivers fault information back to the shift register. The output drivers have low ON voltage at rated current, and are monitored by a comparator for an out of saturation condition, in which case the output driver with the fault becomes unlatched and diagnostic data is sent to the microcomputer via the MISO line. A typical microcomputer interface circuit is shown in Figure 3. CE High to Low Transition When CE is low the three-state MISO pin is enabled. On the falling edge of CE, diagnostic and status data from the output voltage comparators will be latched into the shift register. During the time that CE is low, data bytes controlling the output drivers are shifted in at the MOSI pin most significant bit (MSB) first. Tables 1, 2 and 3 define the logic state for control of each output and Table 4 defines the control bit structure. CE Low to High Transition When the last serial data bit has been shifted into the MOSI pin, CE pin is pulled high to transfer data from the shift register into the 8-bit parallel output latch to activate the outputs. The serial clock input pin (SCK) should be low during CE transitions to avoid false clocking of the shift register. The SCK input is gated by CE so that the SCK input is ignored when CE is high. 4-7 HIP0045 Detecting Fault Conditions Fault conditions may be checked as follows: SCK is always low when CE is changing. When CE goes low, the MISO output is taken out of the three-state mode and the Output status information is latched into the shift register. While CE is low, data bits in the shift register are transferred to the MISO output on each positive SCK clock transition and data bits present at the MOSI input are transferred into the shift register on each negative transition of SCK. To verify Status and Diagnostic conditions, clock in a new control byte and wait approximately 150s to allow the outputs to settle. Clock in the same control byte and compare this to the data output at the MISO pin. If there is a disparity, use Tables 5, 6 and 7 to determine the fault or status condition. (Use Tables 1, 2, 3 and 4 to establish the ON/OFF conditions for each output). Based on the needs of the application, a software sequence should be programmed into the microcontroller to set the corrective action of each fault condition. TABLE 5. DIAGNOSTIC FAILURE REGISTER STRUCTURE Diag1 (D7O) MSB NOTE: ENERGY (mJ) Special Conditions for Channel 0, 1 Referring to the Detailed Block Diagram, Channel's 0, 1 are configured to externally provide control of the ON/OFF state. The inputs, IN0 and IN1, are ORed with the SPI ON/OFF control bit. In this configuration with IN0 and IN1 high, SPI control latches Diag0 and Diag1 as status bits. When the IN0 and IN1 inputs are active, a fault condition is detected by a comparison of IN0 and IN1 to OUT0 and OUT1 respectively causing the Fault Detector to latch a fault bit. The resulting Fault output is latched as diagnostic bit, Diag0 or Diag1. The Diag0 and Diag1 outputs give the status or fault condition of the output drivers as shown in Table 6. Fault detection is disabled during switching/settling time. The Diag0 and Diag1 bits from Channel 0 and 1 respectively indicate a fault when the FAULT BIT is Low, given IN1 and IN0 control. Otherwise Diag0 and Diag1 are status bits when controlled by the SPI input. Note that the SPI Bit, given in Tables 1 and 2 overrides the ON state control from IN0 and IN1. 1000 Diag3 (D6O) Diag5 (D5O) Diag7 (D4O) Diag0 (D3O) Diag2 (D2O) Diag4 (D1O) Diag6 (D0O) LSB 10.
