Overview
The DRV8816PWPR, produced by Texas Instruments, is a versatile and highly integrated DMOS dual 1/2-H-bridge motor driver. This device is designed to drive one brushed DC motor or one winding of a stepper motor, as well as other loads such as solenoids. It features a simple INx/ENx interface for easy integration with controller circuits. The DRV8816PWPR is capable of peak output currents up to ±2.8 A and operates within a supply voltage range of 8 V to 38 V. An internal charge pump generates the necessary gate drive voltages, and the device includes a low-power sleep mode to minimize quiescent current draw.
