Description
The VND670SP is a monolithic device made using STMicroelectronics VIPower technology M0-3, intended for driving motors in full bridge configuration. The device integrates two 30 mW 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 shutdown, 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.
