Unipolar Stepper Motor Driver using a Bipolar Stepper Motor Controller Reference Design

TIDA-00872

Design files

Overview

TIDA-00872 demonstrates how to reconfigure the DRV8711 bipolar stepper motor gate driver as a unipolar stepper motor gate driver. The PCB connects to the MSP430G2 LaunchPad to allow quick evaluation and tuning. The PCB operates from 15V up to 40V, with full scale current of 5A.

Features
  • 15 to 40-V operating supply voltage range with up to 4-A full-scale continuous motor current
  • Up to 1/256 microstep modes depending on motor speed
  • BOOST-DRV8711 GUI for driver input control and motor tuning
  • Onboard USB communication for easy connectivity with external controller
  • Plugs into MSP430G2 LaunchPad
