Overview

The DRV8701PRGER is a smart gate driver designed to control four external N-channel MOSFETs in a single H-bridge configuration for brushed DC motors. Operating from 5.9V to 45V, it integrates a current shunt amplifier, PWM regulation, and adjustable gate drive settings to optimize switching performance.

Why Choose This Part

It offers five levels of adjustable gate drive strength to fine-tune EMI and switching losses without hardware changes. The integrated current shunt amplifier (20 V/V) and PWM regulation simplify the implementation of motor current limiting and torque control.

Applications

Industrial Robotics
Driving high-power brushed DC motors in robotic arms and automated guided vehicles using external MOSFETs for scalable current handling.
White Goods
Precise control of motors in appliances where integrated current sensing and PWM regulation reduce external component count.
Power Tools
Managing high inrush currents and providing robust protection features for battery-operated handheld tools.

Getting Started

Evaluation can be performed using the DRV8701EVM module, which provides a complete hardware environment to test motor control logic. Implementation requires an external MCU to provide PWM signals and monitor the nFAULT pin for overcurrent, thermal, or undervoltage conditions.
