DRV8821DCAR TI Stepper Motor Driver | 48-HTSSOP | 2.5A, 45V

Product Overview

The DRV8821DCAR from Texas Instruments is a dual-bridge stepper motor driver IC designed for bipolar stepper motors. It integrates two H-bridge drivers with current sensing and regulation, capable of driving up to 2.5 A per bridge (with proper heat sinking) and operating from 8.2 V to 45 V supply. The device features microstepping up to 1/32 step, adjustable current decay modes, and protection features including overcurrent, overtemperature, and undervoltage lockout. Housed in a 48-pin HTSSOP package with exposed thermal pad, it is suitable for industrial and automotive applications requiring precise motion control.
