2 Introduction

The DRV8428x EVM is a platform to support prototyping and evaluation for the DRV8428x devices, a medium-voltage dual H-bridge driver for stepper driving applications. The DRV8428x drives a single bipolar stepper with microstepping resolutions down to 1/256. It provides a variety of programmable decay settings.

The EVM uses an MSP430™ microcontroller and a USB interface chip to manage communication from the GUI software application installed on a PC computer with Windows®. The GUI sends serial commands to the MSP430 to control the device signals, monitor faults, read and write SPI registers, and drive a motor.

This user's guide details the hardware configurability of the evaluation module.
