DRV8817DAPR TI Stepper Motor Driver | 2.5A, 8-45V, Microstepping

Product Overview

The DRV8817DAPR from Texas Instruments is a dual-bridge motor driver IC designed for bipolar stepper motors and brushed DC motors. It integrates two N-channel power MOSFET H-bridges, charge pump regulator, current sensing, and protection circuitry. The device operates from 8V to 45V supply voltage and can deliver up to 2.5A peak current per bridge. It supports microstepping with up to 1/32 step resolution, making it suitable for precise motion control applications.
