How To Use DRV8833

The DRV8833 is a dual channel H-bridge motor driver, that can drive two DC motors or one stepper motor. It can supply up to 2A peak current and has internal overcurrent protection. DRV8833 dual DC motor control circuit diagram shown below,

The motors are controlled using the AIN1/2 and BIN1/2 pins. The speed of the motor cannot be controlled, only the direction can. The table below shows the functions each pin state provides.

	AIN1/BIN1	AIN2/BIN2
Forward	HIGH	LOW
Reverse	LOW	HIGH
Brake/Stop	LOW	LOW
Brake/Stop	HIGH	HIGH

The DRV8833 can also be used to drive stepper motors with the following circuit diagram.
