The VNH3ASP30-E is a full-bridge Motor Driver incorporates a dual monolithic high-side driver (HSD) and two low-side switches. The HSD switch is designed using STMicroelectronics proprietary VIPower™ M0 technology that efficiently integrates a true Power MOSFET with an intelligent signal/protection circuit on the same die. The low-side switches are vertical MOSFETs manufactured using STMicroelectronics proprietary EHD (STripFET™) process. It is specifically designed for the harsh automotive environment, offers improved thermal performance thanks to exposed die pads. Moreover, its fully symmetrical mechanical design provides superior manufacturability at board level. The input signals INA and INB can directly interface with the microcontroller to select the motor direction and the brake condition. Pins DIAGA/ENA or DIAGB/ENB, when connected to an external pull-up resistor, enable one leg of the bridge. It also provide a feedback digital diagnostic signal.
