00 — Overview

What the DRV8844 does

The DRV8844 is a quad half-bridge driver IC designed to control DC motors, stepper motors, solenoids, or other loads. It features four individually controllable 1/2-bridge drivers with N-channel power MOSFETs, supporting up to 2.5A peak current at 24V. The device operates across an 8V to 60V supply range and includes built-in 3.3V LDO regulation. Floating input buffers allow dual supply operation, while internal protection handles overcurrent, short circuits, and overtemperature. Typically used in textile, office automation, gaming, factory automation, and robotics applications, the DRV8844 provides full individual half-bridge control in a thermally enhanced 28-pin HTSSOP package.
