DRV8434AQWRGERQ1 TI Stepper Motor Driver | 24-VQFN(4x4) | 2.5A, 32V

Product Overview

The DRV8434AQWRGERQ1 is a automotive-grade, dual H-bridge stepper motor driver from Texas Instruments. It integrates two N-channel power MOSFET H-bridges, current sensing, and protection circuitry. Designed for bipolar stepper motors, it delivers up to 2.5A peak current per bridge (with proper heat sinking) and operates from 4.5V to 32V supply voltage. The device supports microstepping up to 1/256 step, providing smooth motion and high positional accuracy. It features a simple STEP/DIR interface, making it easy to control with a microcontroller. The 24-VQFN (4x4) package is compact and suitable for space-constrained automotive and industrial applications.
