Overview

The DRV8844A evaluation module (EVM) allows for easy evaluation of the DRV8844A motor driver. The EVM has been programmed and configured to work out of the box and begin spinning motors right away. The EVM showcases a quad 1/2 H-Bridge DC motor driver that can drive up to four solenoids, two brushed-DC motors, and other loads. The DRV8844A also supports the connection of sense resistors on each individual Half-Bridge enabling current sensing at system level for applications such as motor control.

Features
  • Onboard 3.3V buck converter for digital voltage supply
  • Main signal header with removable shunts to disconnect main signals going to the motor driver IC from the MCU
  • Onboard switches to select direction and decay mode
  • Onboard potentiometers to control speed of motor
  • Floating input buffers allow dual (bipolar) supplies (up to ±32.5V)
  • Separate power grounds for connection of sense resistors
