Texas Instruments DRV8428EVM Motor Driver Evaluation Module (EVM) allows for easy evaluation of the DRV8428. The DRV8428 is an integrated motor-driver solution for bipolar stepper motors. The device integrates two N-channel power MOSFET H-bridges, integrated current sense, regulation circuitry and a microstepping indexer. The Texas Instruments DRV8428 devices can be powered with a supply voltage from 4.5V to 33V. 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.
