DRV8821DCA TI Stepper Motor Driver | 48-HTSSOP | 2.5A, 45V

Product Overview

The DRV8821DCA 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, adaptive blanking, and stall detection. Housed in a 48-pin HTSSOP package with exposed pad for thermal dissipation, it is ideal for precise motion control in industrial and automotive applications.
