EV-VNHD7008AY

EV-VNHD7008AY VNHD7008AY Evaluation board Data brief Features Symbol Value Unit Max transient supply voltage VCC 38 V Operating voltage range VCC 4 to 28 V Typ.on-state resistance RON per channel 8 mΩ Current limitation (typ) ILIMH 51 A Stand-by current (max) ISTBY 10 µA Parameter  Simple single IC application board dedicated for VNHD7008AY  Provides electrical connectivity and thermal heat-sinking for easy prototyping H-Bridge. On board minimum set of electrical components (as for device datasheet recommendation) is enabling the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection. VNHD7008AY is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a full protected dual high-side driver and the drivers and protections for the two external power MOSFETs in low-side configuration. The device is designed using STMicroelectronics well known and proven proprietary VIPower® technology that allows to efficiently integrate on the same die a true PowerMOSFET with an intelligent signal/ protection circuitry. The device is housed in a PowerSSO-36 exposed pad package to optimize the dissipation performances. The input signals INA and INB can directly interface the microcontroller to select the motor direction and the brake conditions. Two selection pins (SEL0 and SEL1) are available to address to the microcontroller the information available on the MultiSense. The MultiSense pin allows to monitor the motor current, provides a voltage proportional to the battery value and the information on the temperature of the chip. The integrated protections are: load current limitation, overload active power limitation (with latch-off), overtemperature shutdown (with latch-off) and cross current protection. The PWM, up to 20 KHz, allows to control the speed of the motor in all possible conditions. Table 1.
