DRV8434EPWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 32V, 1/256 Microstepping

Product Overview

The DRV8434EPWPR from Texas Instruments is a highly integrated stepper motor driver designed for precise motion control in industrial and automotive applications. It features dual H-bridge drivers capable of driving up to 2.5 A peak current per bridge (2.0 A RMS) with a wide supply voltage range from 4.5 V to 32 V. The device supports 1/256 microstepping for smooth operation and includes advanced protection features such as overcurrent, overtemperature, and undervoltage lockout. Housed in a compact 28-HTSSOP package, it is ideal for space-constrained designs.
