DRV8814PWP TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 8-45V

Product Overview

The DRV8814PWP from Texas Instruments is a dual-bridge stepper motor driver IC designed for bipolar stepper motors. It integrates two N-channel power MOSFET H-bridges, current sensing, and regulation circuitry. The device operates from 8V to 45V supply voltage and can deliver up to 2.5A peak current per bridge. It features a simple STEP/DIR interface, microstepping capability (up to 1/32 step), and built-in protection features including overcurrent, overtemperature, and undervoltage lockout. The 28-pin HTSSOP package with exposed pad ensures efficient thermal dissipation.
