DRV8876 Single Brushed DC Motor Driver Carrier

This compact breakout board for TI’s DRV8876 motor driver offers a wide operating voltage range of 4.5 V to 37  and can deliver a continuous 1.3 A (3.5 A peak) to a single bidirectional brushed DC motor. The DRV8876 also features integrated current sensing and regulation as well as built-in protection against under-voltage, over-current, and over-temperature. The carrier board adds protection against reverse voltage.

This carrier for TI’s DRV8876PWP motor drier can supply continuous currents up to about 1.3 A and can tolerate peak currents up to 3.5 A. Since this board is a carrier for the DRV8876, we recommend careful reading of the DRV8876 datasheet. The board ships populated with all of its SMD components, including the DRV8876.
