DRV8834PWPR TI Stepper Motor Driver | 24-HTSSOP | 2.5A, 10.8V

Product Overview

The DRV8834PWPR from Texas Instruments is a dual-bridge stepper motor driver capable of driving up to 2.5A per bridge (with proper heat sinking) and operating from 2.5V to 10.8V supply voltage. It integrates two N-channel power MOSFET H-bridges, current sensing, and regulation circuitry. The device is housed in a 24-pin HTSSOP package with an exposed thermal pad for enhanced heat dissipation. It is designed for bipolar stepper motors or two DC motors, offering microstepping up to 1/32 step. The DRV8834PWPR features a simple STEP/DIR interface, adjustable current regulation, and protection features including overcurrent, overtemperature, and undervoltage lockout.
