Overview

The VNH7070BASTR is a fully integrated half-bridge motor driver designed for brushed DC motor control applications. It combines a control stage with power MOSFETs in a single SO-16N package, supporting load voltages from 4V to 28V and delivering up to 15A of output current. The device features integrated PWM control up to 20 kHz and comprehensive diagnostic feedback via an analog current sense pin.

Why Choose This Part

This driver integrates high-side and low-side MOSFETs with built-in protection against cross-conduction, undervoltage, and thermal overload. It offers a remarkably low standby current of 1 uA and provides real-time analog motor current feedback for precise closed-loop control.

Applications

Automotive Body Control
Ideal for power windows, seats, and sunroof actuators requiring AEC-Q100 qualification and robust protection.
Industrial Robotics
Provides efficient brushed DC motor driving for small robotic joints and automated guided vehicle steering.
Power Tools
Small footprint and high current capability make it suitable for cordless drill and driver motor management.
