DRV8833PWP - Bipolar Motor Driver NMOS PWM 16-HTSSOP

Overview

The DRV8833PWP is a dual H-bridge motor driver designed to control two brushed DC motors or one bipolar stepper motor from a 2.7V to 10.8V supply. Each bridge provides up to 1.5A RMS (2A peak) and features integrated PWM current regulation to manage winding current without constant microcontroller intervention.

Why Choose This Part

It offers low MOSFET ON-resistance of 360 mOhm (high-side + low-side) for efficient operation and thermal management. The ability to parallel outputs allows the device to drive a single motor at up to 3A RMS, providing flexibility for different load requirements within the same footprint.

Applications

Battery-Powered Robotics

Driving small mobile robot chassis and actuators from Li-ion or NiMH battery packs due to the low 2.7V minimum operating voltage.

Bipolar Stepper Motors

Providing phase control and current limiting for small NEMA 11 or NEMA 14 stepper motors used in precision positioning.

Solenoid and Valve Actuation

Controlling high-current inductive loads in industrial automation or smart irrigation systems.

Handheld POS Terminals

Driving thermal printer mechanisms and paper feed motors in portable consumer electronics.
