Overview

The DRV8872DDARQ1 is an automotive-qualified H-bridge motor driver designed to control one bidirectional brushed DC motor or a unipolar stepper motor. It operates over a wide supply range from 6.8V to 45V and can deliver up to 3.6A of peak output current. The device features integrated current regulation and a low-power sleep mode that reduces current consumption to 13uA.

Why Choose This Part

The IC simplifies design by integrating current regulation using an internal reference voltage, eliminating the need for an external shunt resistor in many cases. It provides robust protection with integrated undervoltage lockout, overcurrent protection, and thermal shutdown, all reported through a dedicated fault pin.

Applications

Automotive Actuators
Ideal for HVAC flap motors, power mirrors, and electronic throttle control systems requiring AEC-Q100 qualification.
Industrial Robotics
Used in small robot joints and pick-and-place head movements where integrated current limiting is necessary.
Battery-Powered Tools
Efficient motor control for cordless appliances that benefit from ultra-low power sleep states to preserve battery life.

Getting Started

Designers can evaluate the part using the DRV8872-Q1 Evaluation Module (EVM) to test PWM control logic and thermal performance. Connect the VM pin to a 6.8V-45V supply and provide logic-level PWM signals to the IN1 and IN2 pins to control motor direction and speed.
