DRV8844

Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This TI datasheet covers the DRV8844, a quad half-bridge motor driver IC. It is designed to control four solenoids, two DC motors, one stepper motor, or other loads. Key features include 2.5A maximum drive current at 24V, floating input buffers for dual supplies up to ±30V, and a built-in 3.3V LDO regulator. The device operates across an 8V to 60V supply range with industry-standard digital control interfaces. It includes internal protection for overcurrent, short circuits, undervoltage, and overtemperature conditions. Available in a 28-pin HTSSOP package, it supports parallel output connections and thermal enhancement.
