VNHD7008AY H-bridge motor driver for automotive DC motor driving Datasheet - production data MultiSense diagnostic functions Output short to ground detection Thermal shutdown indication PowerSSO-36 GAPGCFT00004 OFF-state open-load detection Output short to V detection CC Features Standby mode Half bridge operation Type R I V Charge pump output for reverse battery DS(on) out CCmax protection 8 mtyp VNHD7008AY 51 A 38 V Package: ECOPACK per channel) Description AEC-Q100 qualified Output current: 51 A The device is a DC motor driver for automotive applications. It integrates a full protected dual Dual fully protected HSD with MultiSense high-side driver and the drivers and protections feedback for the two external power MOSFETs in low-side Two integrated drivers for the external LSDs configuration. 3 V CMOS compatible inputs The device is designed using STMicroelectronics Protections: well known and proven proprietary VIPower M0 Undervoltage shutdown technology that allows to efficiently integrate on the same die a true PowerMOSFET with an Overvoltage clamp intelligent signal/ protection circuitry. The device Thermal shutdown is housed in a PowerSSO-36 exposed pad Load current limitation package to optimize the dissipation Self-limiting of fast thermal transients performances. (Power Limitation) The input signals IN and IN can directly A B Cross current protection interface the microcontroller to select the motor Shoot through protection direction and the brake conditions. Two selection Loss of ground and loss of V CC pins (SEL0 and SEL1) are available to address to Electrostatic discharge protection the microcontroller the information available on Drain and source voltage monitoring of the the MultiSense. The MultiSense pin allows to external power MOSFETs, configurable via monitor the motor current, provides a voltage an external resistance (short-to-battery proportional to the battery value and the protection) information on the temperature of the chip. The integrated protections are: load current limitation, PWM operation up to 20 kHz for external LSDs overload active power limitation (with latch-off), MultiSense monitoring functions overtemperature shutdown (with latch-off) and Analog motor current feedback cross current protection.
