DRV8421BDFUR TI Stepper Motor Driver | 10-SSOP | 2.5A, 48V

Product Overview

The DRV8421BDFUR from Texas Instruments is a dual-bridge stepper motor driver IC designed for precise and efficient control of bipolar stepper motors. It integrates two H-bridge drivers with current sensing and regulation, capable of driving up to 2.5A peak current per bridge and operating from 4.5V to 48V supply voltage. The device is housed in a compact 10-pin SSOP package, making it ideal for space-constrained applications. It features advanced current decay modes, microstepping capability, and protection features such as overcurrent, overtemperature, and undervoltage lockout.
