Dual High Resolution Micro-stepping Driver Reference Design

TIDA-00641

Design files

Overview

This reference design achieves a dual channel high resolution micro-stepping driver module using PWM current regulation method. Selectable micro-stepping level and current level is provided with the on-board switches. The PWM regulation scheme gives smooth phase current and ultra-low acoustic operation noise. Protections such as over current, over temperature, and short outputs are all provided along with the DRV8848 device.

Features
  • Smooth current and low acoustic noise
  • Up to 1/256 micro-stepping level
  • Selectable micro-stepping and current level
  • Easy STEP/DIR interface
  • Compact dual channel design
  • Full protections

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
