The device integrates two 30 m Power MOSFET in high side configuration, and provides gate drive for two external Power MOSFET used as low side switches. INA and INB allow to select clockwise or counter clockwise drive or brake; DIAGA/ENA, DIAGB/ENB allow to disable one half bridge and feedback diagnostic. Built-in thermal shut-down, combined with a current limiter, protects the chip in overtemperature and short circuit conditions. Short to battery protects the external connected low-side Power MOSFET.

Layout hints: The connection between GND pin of the VN670SP and the Power MOSFET SOURCE connections should be kept short enough to ensure that the dynamic difference between these two points never exceed 1V for the bridge to operate properly. 5/14 VND670SP TYPICAL APPLICATION CIRCUIT FOR A 20KHZ PWM OPERATION +5V R1 Rprot 1K +5V VCC R1 Rprot 1K DIAGA/ENA DIAGB/ENB VND670SP Rprot 1K INA OUTA Rgnd(*) OUTB Rprot 1K Rprot PWM GATEA UP M D1 D2 INB GATEB 1K DOWN 27 External Power Mos A External Power Mos B 27 (*) Reverse battery protection: - series relay in VCC line: Rgnd=0 Ohms - series fuse in VCC line with antiparallel diode between ground and VCC: Rgnd=10 Ohms. 6/14 VND670SP WAVEFORMS AND TRUTH TABLE (CONTINUED) In case of a fault condition the DIAGX/ENX pin is considered as an output pin by the device. The fault conditions are: - overtemperature on one or both high sides; - short to battery condition on the output (saturation detection on the external connected Power MOSFET). Possible origins of fault conditions may be: OUTA is shorted to ground ---> overtemperature detection on high side A. OUTA is shorted to VCC ---> external Power MOSFET saturation detection (driven by GATEA). When a fault condition is detected, the user can know which power element is in fault by monitoring the INA, INB, DIAGA/ ENA and DIAGB/ENB pins. In any case, when a fault is detected, the faulty half bridge is latched off. To turn-on the respective output (GATEX or OUTX) again, the input signal must rise from low to high level.

In the test mode (Vpwm=-2V) the external Power Mos gate drivers are disabled. The INA or INB inputs allow to turn-on the High Side A or B, respectively, in order to connect one side of the load at VCC voltage. The check of the voltage on the other side of the load allow to verify the continuity of the load connection. In case of load disconnection the DIADX/ENX pin corresponding to the faulty output is pulled down. 7/14 VND670SP ELECTRICAL TRANSIENT REQUIREMENTS ISO T/R 7637/1 Test Pulse 1 2 3a 3b 4 5 ISO T/R 7637/1 Test Pulse 1 2 3a 3b 4 5 Class C E Test Level I -25V +25V -25V +25V -4V +26.5V Test Level II -50V +50V -50V +50V -5V +46.5V Test Level III -75V +75V -100V +75V -6V +66.5V Test Level IV -100V +100V -150V +100V -7V +86.5V Test Levels Result III C C C C C E Test Levels Delays and Impedance 2ms, 10 0.2ms, 10 0.1s, 50 0.1s, 50 100ms, 0.01 400ms, 2 Test Levels Result IV C C C C C E Test Levels Result I C C C C C C Test Levels Result II C C C C C E Contents All functions of the device are performed as designed after exposure to disturbance.
