DRV8885RHRT TI Stepper Motor Driver | 28-WQFN (5.5x3.5) | 2.5A, 45V

Product Overview

The DRV8885RHRT from Texas Instruments is a highly integrated stepper motor driver with dual H-bridge outputs, capable of driving up to 2.5 A peak current per bridge and operating from 8 V to 45 V supply voltage. It features advanced current regulation, microstepping up to 1/32 step, and a simple STEP/DIR interface. The device is housed in a compact 28-pin WQFN package (5.5 mm x 3.5 mm) with exposed thermal pad for efficient heat dissipation. It includes protection features such as overcurrent, overtemperature, and undervoltage lockout.
