DRV8833 2 Channel DC Motor Driver

The DRV8833 is a dual H-bridge motor driver IC designed for bidirectional control of two brushed DC motors within a voltage range of 2.7 V to 10.8 V. With the ability to continuously supply up to approximately 1.2 A per channel and tolerate peak currents of up to 2 A per channel for short durations, it’s particularly suited for driving small motors operating on lower voltages. The board comes pre-assembled with surface mount components, including the DRV8833, and incorporates a FET for reverse battery protection, enhancing its reliability.

Compared to similar drivers, the DRV8833 boasts a higher peak current rating of 2 A per channel, optional built-in current-limiting functionality, and doesn’t require an externally supplied logic voltage, simplifying its usage and integration into motor control systems.

Features:

1. Dual-H-bridge motor driver: can drive two DC motors or one bipolar stepper motor
2. Operating voltage: 2.7‌‌ V to 10.8 V
3. Output current: 1.2 A continuous (2 A peak) per motor
4. Motor outputs can be paralleled to deliver 2.4 A continuous (4 A peak) to a single motor
5. Inputs are 3V- and 5V-compatible
6. Under-voltage lockout and protection against over-current and over-temperature
7. Reverse-voltage protection circuit
8. Current limiting can be enabled by adding sense resistors (not included)
