DRV8434RGER TI Stepper Motor Driver | 24-VQFN (4x4) | 2.5A, 4.5-48V

Product Overview

The DRV8434RGER from Texas Instruments is a dual H-bridge motor driver designed for bipolar stepper motors or two brushed DC motors. It integrates N-channel power MOSFETs with a low RDS(on) of 0.25 Ω per FET, enabling high efficiency and up to 2.5 A peak current per bridge. The device operates from a supply voltage range of 4.5 V to 48 V, making it suitable for a wide variety of industrial and consumer applications. The 24-pin VQFN (4x4 mm) package offers a compact solution for space-constrained designs.
