DRV8425PWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 4.5-33V

Product Overview

The DRV8425PWPR from Texas Instruments is a dual-bridge stepper motor driver with integrated current sensing and microstepping capability. It is designed to drive one bipolar stepper motor or two brushed DC motors with up to 2.5A peak current per bridge. The device operates from a supply voltage range of 4.5V to 33V and features a 28-pin HTSSOP package with exposed thermal pad for enhanced heat dissipation. The DRV8425PWPR incorporates advanced protection features including overcurrent, overtemperature, and undervoltage lockout, making it suitable for industrial and automotive applications.
