Overview
The DRV8833PWPR, produced by Texas Instruments, is a dual H-bridge motor driver integrated circuit designed for driving brushed DC motors, bipolar stepper motors, solenoids, or other inductive loads. This device is particularly suited for applications in toys, printers, video security cameras, office automation machines, gaming machines, and robotics. It features two H-bridge drivers, each capable of regulating or limiting the winding current, and includes internal shutdown functions for overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature protection. The DRV8833 also includes a low-power sleep mode to conserve energy when not in use.
