DRV8833 2 Channel DC Motor Driver - Motor Driver IC for Small Motors

DRV8833 2 Channel DC Motor Driver is a powerful solution designed for bidirectional control of two brushed DC motors or a bipolar stepper motor, making it suitable for mobile robots. Operating at a voltage range of 2.7 V to 10.8 V, it provides a continuous output current of 1.2 A per channel and can handle peak currents up to 2 A per channel for short periods. This makes it exceptionally well-suited for small to medium-sized motors that require low voltage yet effective operation. The L298N and L293D motor driver alternatives are also popular in similar applications, offering varied features for DC drive motor speed control.
