The IC generates its own low supply voltage for the internal circuitry. Therefore an additional low voltage supply is not required. A capacitor has to be connected to pin VDD to obtain a ripple-free internal supply voltage. The circuit can also be powered by a low voltage supply directly applied to pin VDD. In this case pin HV should be connected to pin VDD or SGND. Start-up With an increasing supply voltage the IC enters the start-up state; the higher power transistors are kept off and the lower power transistors are switched on. During the start-up state the bootstrap capacitors are charged and the bridge output current is zero. The start-up state is defined until VDD = VDD(UVLO), where UVLO stands for Under Voltage Lock-out. The state of the outputs during the start-up phase is overruled by the bridge disable function. Release of the power drive At the moment the supply voltage on pin VDD or HV exceeds the level of release power drive, the output voltage of the bridge depends on the control signal on pin EXTDR (see Table 1). The bridge position after start-up, disable, or delayed start-up (via pin SU) depends on the status of the pins DD and EXTDR. If pin DD = LOW (divider enabled) the bridge will start in the pre-defined position: pin GLR and pin GHL = HIGH and pin GLL and pin GHR = LOW. If pin DD = HIGH (divider disabled) the bridge position will depend on the status of pin EXTDR. If the supply voltage on pin VDD or HV decreases and drops below the reset level of power drive the IC enters the start-up state again. Oscillation At the point where the supply voltage on pin HV crosses the level of release power drive, the bridge begins commutating between the following two defined states: * Higher left and lower right MOSFETs on, higher right and lower left MOSFETs off * Higher left and lower right MOSFETs off, higher right and lower left MOSFETs on. The oscillation can take place in three different modes: * Internal oscillator mode. UBA2033 In this mode the bridge commutating frequency is determined by the values of an external resistor (Rosc) and capacitor (Cosc). In this mode pin EXTDR must be connected to pin +LVS. To realize an accurate 50% duty factor, the internal divider should be used. The internal divider is enabled by connecting pin DD to SGND. Due to the presence of the divider the bridge frequency is half the oscillator frequency. The commutation of the bridge will take place at the falling edge of the signal on pin RC. To minimize the current consumption pins +LVS, -LVS and EXTDR can be connected together to either pin SGND or VDD. In this way the current source in the logic voltage supply circuit is shut off. * External oscillator mode without the internal divider. In the external oscillator mode the external source is connected to pin EXTDR and pin RC is short-circuited to pin SGND to disable the internal oscillator. If the internal divider is disabled (pin DD = VDD) the duty factor of the bridge output signal is determined by the external oscillator signal and the bridge frequency equals the external oscillator frequency. * External oscillator mode with the internal divider. The external oscillator mode can also be used with the internal divider function enabled (pin RC and pin DD = SGND). Due to the presence of the divider the bridge frequency is half the external oscillator frequency. The commutation of the bridge is triggered by the falling edge of the EXTDR signal with respect to V-LVS. The design equation for the bridge oscillator frequency is: 1 f bridge = -------------------------------------------------( k osc x R osc x C osc ) Non-overlap time The non-overlap time is the time between turning off the conducting pair of MOSFETs and turning on the next pair. The non-overlap time is internally fixed to a very small value, which allows an HID system to operate with a very small phase difference between load current and full bridge voltage (pins SHL and SHR). Especially when igniting an HID lamp via a LC resonance circuit, a small `dead time' is essential. The high maximum operating frequency, together with a small `dead time', also gives the opportunity to ignite the HID lamp at the third harmonic of the full bridge voltage, thereby reducing costs in the magnetic power components. 2002 Oct 08 5 Philips Semiconductors Product specification HF full bridge driver IC 'Dead time' can be increased by adding a resistor (for slowly turning on the full bridge power FETs) and a diode (for quickly turning off the full bridge power FETs) in parallel, both in series with the gate drivers (see Fig.3). Divider function If pin DD = SGND, then the divider function is enabled/present. If the divider function is present there is no direct relation between the position of the bridge output and the status of pin EXTDR. Start-up delay Normally, the circuit starts oscillating as soon as pin VDD or HV reaches the level of release power drive. At this Table 1 Logic table; note 1 INPUTS BD HIGH LOW Oscillation state HIGH LOW LOW LOW SU X X X LOW HIGH HIGH DD X X X X HIGH LOW EXTDR X X X X HIGH LOW LOW LOW-to-HIGH HIGH HIGH-to-LOW Note 1. X = don't care a) BD, SU and DD logic levels are with respect to SGND b) EXTDR logic levels are with respect to V-LVS c) GHL logic levels are with respect to SHL d) GHR logic levels are with respect to SHR e) GLL and GLR logic levels are with respect to PGND LOW HIGH GHL LOW LOW LOW LOW LOW HIGH HIGH OUTPUTS GHR LOW LOW LOW LOW HIGH LOW LOW UBA2033 moment the gate drive voltage is equal to the voltage on pin VDD for the low side transistors and VDD - 0.6 V for the high side transistors. If this voltage is too low for sufficient drive of the MOSFETs the release of the power drive can be delayed via pin SU. A simple RC filter (R between pins VDD and SU; C between pins SU and SGND) can be used to make a delay, or a control signal from a processor can be used. Bridge disable The bridge disable function can be used to switch off all the MOSFETs as soon as the voltage on pin BD exceeds the bridge disable voltage (1.29 V). The bridge disable function overrules all the other states.

The bridge disable, the start-up delay and the external drive functions are not used in this application. The pins -LVS, +LVS, EXTDR and BD are short-circuited to SGND. The internal oscillator is used and to realize a 50% duty cycle the internal divider function has to be used UBA2033 by connecting pin DD to SGND. The IC is powered by the high voltage supply. Because the internal oscillator is used, the bridge commutating frequency is determined by the values of Rosc and Cosc. The bridge starts oscillating when the HV supply voltage exceeds the level of release power drive (typically 12.5 V on pin HV). If the supply voltage on pin HV drops below the reset level of power drive (typically 10 V on pin HV), the UBA2033 enters the start-up state. handbook, full pagewidth high voltage 550 V (max) R>100 1 2 3 6 9 10 11 12 13 14 23 GLR PGND GLL SHL FSL GHL C2 28 27 26 GHR FSR SHR C1 R>100 LR IGNITOR LL R>100 HR HL R>100 -LVS EXTDR +LVS HV VDD Ci Rosc C3 SU DD BD RC SGND Cosc UBA2033TS 21 20 17 16 15 GND MBL459 Fig.3 Basic configuration. 2002 Oct 08 10 Philips Semiconductors Product specification HF full bridge driver IC Application with external control Figure 4 shows an application containing a system ground-referenced control circuit. Pin +LVS can be connected to the same supply as the external oscillator control unit and pin -LVS is connected to SGND. Pin RC is UBA2033 short-circuited to SGND. The bridge commutation frequency is determined by the external oscillator. The bridge disable input (pin BD) can be used to immediately turn off all four MOSFETs in the full bridge. handbook,high voltage full pagewidth 550 V (max) R>100 1 2 3 6 9 10 11 12 13 14 23 GLR PGND GLL SHL FSL GHL C2 28 27 26 GHR FSR SHR C1 R>100 LR IGNITOR LL R>100 HR HL R>100 low voltage -LVS EXTDR +LVS HV VDD SU DD BD RC SGND C3 Ci EXTERNAL OSCILLATOR CONTROL CIRCUIT UBA2033TS 21 20 17 16 15 GND MBL460 Fig.4 External control configuration. 2002 Oct 08 11 Philips Semiconductors Product specification HF full bridge driver IC Additional application information GATE RESISTORS At ignition of an HID lamp, a large EMC spark occurs. This can result in a large voltage transient or oscillation at the gates of the full bridge MOSFETs (LL, LR, HR and HL). When these gates are directly coupled to the gate drivers (pins GHR, GLR, GHL and GLL), voltage overstress of the driver outputs may occur. Therefore it is advised to add a resistor with a minimum value of 100 in series with each gate driver to isolate the gate driver outputs from the actual power MOSFETs gate. 'Dead time' can also be adjusted via the combination gate resistor and gate-source capacitance. UBA2033 GATE CHARGE AND SUPPLY CURRENT AT HIGH FREQUENCY USE The total gate current needed to charge the gates of the power MOSFETs equals: I gate = 4 x f bridge x Q gate Where: Igate = gate current fbridge = bridge frequency Qgate = gate charge. This current is supplied via the internal low voltage supply (VDD). Since this current is limited to 11 mA (see "Characteristics" table note 1), at higher frequencies and with MOSFETs having a relative high gate charge, this maximum VDD supply current may not be sufficient anymore. As a result the internal low voltage supply (VDD) and the gate drive voltage will drop resulting in an increase of the higher resistance (Ron) of the full bridge MOSFETs. In this case an auxiliary low voltage supply is necessary. 2002 Oct 08 12 Philips Semiconductors Product specification HF full bridge driver IC PACKAGE OUTLINE SSOP28: plastic shrink small outline package; 28 leads; body width 5.3 mm UBA2033 SOT341-1 D E A X c y HE vMA Z 28 15 Q A2 pin 1 index A1 (A 3) Lp L 1 e bp 14 wM detail X A 0 2.5 scale 5 mm DIMENSIONS (mm are the original dimensions) UNIT mm A max. 2.0 A1 0.21 0.05 A2 1.80 1.65 A3 0.25 bp 0.38 0.25 c 0.20 0.09 D (1) 10.4 10.0 E (1) 5.4 5.2 e 0.65 HE 7.9 7.6 L 1.25 Lp 1.03 0.63 Q 0.9 0.7 v 0.2 w 0.13 y 0.1 Z (1) 1.1 0.7 8 0o o Note 1.

A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 220 C for thick/large packages, and below 235 C for small/thin packages. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. UBA2033 If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 2002 Oct 08 14 Philips Semiconductors Product specification HF full bridge driver IC Suitability of surface mount IC packages for wave and reflow soldering methods UBA2033 SOLDERING METHOD PACKAGE WAVE BGA, HBGA, LFBGA, SQFP, TFBGA HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, SMS PLCC(3), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. not suitable not not not suitable(2) recommended(3)(4) recommended(5) suitable REFLOW(1) suitable suitable suitable suitable suitable 2002 Oct 08 15 Philips Semiconductors Product specification HF full bridge driver IC DATA SHEET STATUS LEVEL I DATA SHEET STATUS(1) Objective data PRODUCT STATUS(2)(3) Development DEFINITION UBA2033 This data sheet contains data from the objective specification for product development.
