Overview

The DRV8424 evaluation module (EVM) allows easy evaluation of the DRV8424 device.

The DRV8424 devices are integrated motor-driver solutions for bipolar stepper motors. The device integrates two N-channel power MOSFET H-bridges, integrated current sense and regulation circuitry, and a microstepping indexer. The DRV8424 devices can be powered with a supply voltage from 4.5 to 33 V. A simple STEP/DIR control interface allows for an external controller to manage the outputs. The decay mode can be selected as a slow, mixed decay, smart tune Ripple Control, or smart tune Dynamic Decay current regulation scheme.

For more information on this evaluation module please refer to the DRV84xxEVM User's Guide.
