Overview

The TIDA-00867 reference design showcases the benefits of integrated current sensing for stepper motors. Integraded current sensing is available on the DRV8885. The DRV8885EVM to demonstrate this feature.

Features
  • 8.0- to 37-V operating supply voltage range with up to 1.5-A full-scale continuous motor current
  • Integrated current sense functionality
  • No sens resistors required
  • ±6.25% full-scale current accuracy
  • Simple GUI for driver input control and motor tuning
  • Onboard USB communication for easy connectivity with external controller
  • 100 mil header gives test probe access to all driver input controls
