2.1 Introduction

This document is provided as a supplement to the DRV8844A data sheet. The document details the hardware implementation of the DRV8844AEVM customer evaluation module (EVM).

The DRV8844A customer evaluation module (EVM) is a platform revolving around the DRV8844A, a medium voltage, quadruple half-H-bridge driver. This device is designed to drive four independent inductive or resistive loads, such as solenoids, relays, or lamps. The EVM can also drive two brushed DC motors. The EVM houses an MSPM0 microcontroller with a 10-pin connector for flashing firmware. The EVMs are all be preprogramed with firmware. The EVM uses potentiometers and switches to control the speed, direction, and decay mode with onboard LEDs to help visualize which channels are receiving inputs signals. The microcontroller firmware offers the generation of all the control signals often employed to enable or disable the power stage and four PWM’s to articulate each power output with a configurable duty cycle.

This user guide details the operation of the EVM, as well as the hardware configurability of the evaluation module.
