Pinnames in brackets refer to coding pin (COD=Vcc). (3) If COD = Vcc then DI1 and DI2 are not active. (4) In case of over-current, the time when the current is greater than 7,8A is lower than 30µs, with a maximum frequency of 1kHz.

PINS FUNCTION DESCRIPTION Pin Name Description 9, 10, 11, 12 Metal slug GND Power Ground 1 GND Analog ground 2 Output Statusflag (SF) Open drain output, active low. Is set according to the truth table . 3,13 18, 19 Inputs IN1,IN2 DI1,DI2, COD Voltage controlled inputs with hysteresis 8 COD 6, 7, 14, 15 OUT1 , OUT2 4, 5, 16 Vbat When not connected or connected to GND, a stored failure will be reset by change of the voltage-level on DI1 or DI2. When connected to Vcc, the disable pin DI1 and DI2 are inactive. A stored failure will be reset by change of the voltage-level on IN1 or IN2 . H-Bridge outputs with integrated free-wheeling diodes. The pins 4 and 5 are internally connected. These pins supply the left high side and the analogue/logic part of the device. The pin 16 supplies the right high side and the charge pump. The pins 4, 5 and 16 should be connected together on the printed circuit board with connections as short as possible. Supervision and protection functions a) Supply voltage supervision The supply voltage is supervised . If it is below its specific threshold , the power stages are switched in tristate and the status flag is switched low. If the supply voltage is over the specific theshold again , the power stage switches independently into normal operation, according to the input pins and the status flag is reset . b) Thermal supervision In case of over-temperature the power stages are switched in tristate independent of the inputs signals and the status flag is switched low. If the level changes from high to low on DI1 (IN1) or low to high on DI2 ( IN2 ), the output stage switches on again if the temperature is below the specified limit .The statusflag is reset to high level (Pinnames in brackets refer to coding pin=Vcc). c) Supervision of overcurrent If overcurrent is detected the power stages are independent of the inputs signals switched in tristate and the status flag is set . If the level changes from high to low on DI1 ( IN1 ) or low to high on DI2 ( IN2 ) the output stage switches on again and the status flag is reset to high level (Pinnames in brackets refer to coding pin = Vcc). The output stage switches into the mode defined by the inputs pins provided the temperature is below the specified limits . d) Current limiting The maximum current which can flow under normal operating conditions is limited to Imax = 6,5A +/- 20% .When the maximum current value is reached, the output stages are switched tristate for a fixed time. According to the time constant the current decreases until the next switch on occurs. See page 8 for schematics.

PACKAGE INFORMATION The HSOP20 package is designed for enhanced thermal performance. The particularity of this package is its copper baseplate on which the power die is soldered. The baseplate is soldered on a PCB to provide heat flow to the ambient and also to provide a large thermal capacitance. Of course, the more copper area on the PCB, the better the power dissipation and transient behaviour. We characterized the HSOP20 on a double side PCB. The bottom side area of the copper is 7.8 cm2. The top surface is 2.7 cm2, see Figure 22. Figure 22. PCB Test Layout Figure 23.
