DRV8434ARGER TI Stepper Motor Driver | 24-VQFN (4x4) | 2.5A, 4.5-48V

Product Overview

The DRV8434ARGER from Texas Instruments is a dual-bridge motor driver IC designed for bipolar stepper motors. It integrates two N-channel power MOSFET H-bridges, current sensing, and protection circuitry in a compact 24-VQFN (4x4 mm) package. The device operates from a supply voltage range of 4.5 V to 48 V and can deliver up to 2.5 A peak current per bridge. It features a simple STEP/DIR interface, microstepping up to 1/256 step, and advanced current regulation for smooth motion control.
