DRV8434SPWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 32V

Product Overview

The DRV8434SPWPR 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 28-HTSSOP package. The device operates from a supply voltage range of 4.5V to 32V and can deliver up to 2.5A peak current per bridge. It features advanced current regulation with mixed decay mode, allowing smooth and quiet motor operation. The DRV8434SPWPR is ideal for applications requiring precise motion control, such as 3D printers, robotics, and industrial automation.
