Overview
The DRV8801A-Q1 is a versatile motor driver solution produced by Texas Instruments. This device is designed to drive brushed DC motors, one winding of a stepper motor, and other devices such as solenoids. It features a full H-bridge driver configuration using N-channel power MOSFETs, allowing for easy interfacing with controller circuits through a simple PHASE and ENABLE interface. The DRV8801A-Q1 operates within a supply voltage range of 6.5 to 36 V and can provide peak output currents up to ±2.8 A. It includes an internal charge pump to generate the required gate drive voltages and a low-power sleep mode to minimize quiescent current draw.
