DRV8812PWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 8-45V

Product Overview

The DRV8812PWPR from Texas Instruments is a dual-bridge motor driver IC designed for bipolar stepper motors or dual brushed DC motors. It integrates two N-channel power MOSFET H-bridges, current sensing, and regulation circuitry. The device operates from 8V to 45V supply voltage and can deliver up to 2.5A peak current per bridge. It features a simple STEP/DIR interface for stepper motor control and supports 1/8 microstepping. The 28-HTSSOP package with PowerPAD ensures efficient thermal dissipation.
