Dual-channel H-bridge motor driver
The DRV8833PWR is a dual H-bridge motor driver IC from Texas Instruments designed for driving small DC motors, stepper motors, solenoids, and other inductive loads in low-voltage battery-powered systems. It integrates two full H-bridge outputs that allow independent or combined control of two motors or one bipolar stepper motor.
It is commonly used in robotics, toys, printers, and embedded motion-control applications due to its compact size and built-in protection features.
