DRV8881EPWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 45V

Product Overview

The DRV8881EPWPR from Texas Instruments is a highly integrated stepper motor driver with dual H-bridge outputs, capable of driving up to 2.5A peak current per bridge and operating from 8.2V to 45V supply voltage. It features advanced current regulation, microstepping up to 1/32 step, and protection features including overcurrent, overtemperature, and undervoltage lockout. The device is housed in a compact 28-HTSSOP package with exposed thermal pad for enhanced heat dissipation.
