DRV8833EVM - DRV8833 - Motor Controller/Driver,

Overview

The DRV8833EVM is an evaluation module for the DRV8833 dual H-bridge motor driver, designed to control two DC motors or one bipolar stepper motor. It operates over a supply voltage range of 2.7V to 10.8V and can deliver up to 1.33A of output current per channel. The board includes an on-board voltage regulator and LED indicators for fault monitoring.

Why Choose This Part

The module provides a ready-to-use platform for testing the DRV8833's thermal performance and current regulation capabilities. It features an nFAULT LED for immediate visual feedback on overcurrent or over-temperature conditions and an integrated regulator to simplify power rail management during prototyping.

Applications

Battery-Powered Robotics

Ideal for small mobile robots using low-voltage battery packs like Li-Po or NiMH due to its 2.7V minimum operating voltage.

Bipolar Stepper Control

Precise control of small stepper motors in office automation or consumer electronics.

Dual Brushed DC Motors

Independent control of two DC motors for differential drive platforms.

Solenoid Drivers

Driving inductive loads such as low-voltage solenoids and relays with integrated flyback protection.

Getting Started

Connect a power supply between 2.7V and 10.8V to the VIN terminal and interface your microcontroller to the J1 and J2 headers. Use PWM signals on the input pins to control motor speed and direction, while monitoring the nFAULT pin for safety logic. The board layout is optimized for thermal dissipation to allow testing at the maximum rated current of 1.33A.
