This compact breakout board for the TI DRV8833 dual motor driver continuously delivers 1.2 A per channel (2 A peak) to two DC motors. With an operating voltage range of 2.7 V to 10.8 V and built-in reverse voltage, undervoltage, overcurrent, and overtemperature protection, it is an ideal solution for driving small low-voltage motors. The TI DRV8833 is a dual H-bridge motor driver IC capable of bidirectionally controlling two brushed DC motors over a voltage range of 2.7 V to 10.8 V. It continuously delivers approximately 1.2 A per channel and can handle peak currents of up to 2 A per channel for several seconds. This board is a carrier for the DRV8833, comes pre-populated with SMD components including the DRV8833, and adds a FET for reverse battery protection. The board is very similar to our DRV8835 dual motor driver carrier in terms of operating voltage range and continuous current rating; however, the DRV8835 offers a lower minimum operating voltage, additional control interface modes, and is 0.1 inches smaller in each dimension. The DRV8833 features a higher peak current rating (2 A vs. 1.5 A per channel), optional built-in current limiting, and requires no external logic voltage supply. For a smaller, lower-cost single-channel alternative, consider our DRV8838 carrier, which offers a similar operating voltage range and current capability. For higher-voltage alternatives, consider our A4990 and DRV8801 motor driver carriers.
