DRV8805DW TI Motor Driver | 20-SOIC | 2.5A, 36V, Bipolar Stepper

Product Overview

The DRV8805DW from Texas Instruments is a dual H-bridge motor driver IC designed for bipolar stepper motors or two DC motors. It integrates N-channel power MOSFETs with a low on-resistance of 0.55Ω per FET, enabling efficient operation up to 2.5A peak current per bridge and 36V supply voltage. The device features a simple STEP/DIR interface, fixed-frequency current regulation, and built-in protection including overcurrent, overtemperature, and undervoltage lockout. Housed in a 20-pin SOIC package, it is ideal for space-constrained applications requiring precise motor control.
