DRV8874 Single Brushed DC Motor Driver Carrier

This compact breakout board for TI’s DRV8874 motor driver offers a wide operating voltage range of 4.5 V to 37  and can deliver a continuous 2.1 A (6 A peak) to a single bidirectional brushed DC motor. The DRV8874 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 DRV8874PWP motor driver can supply continuous currents up to approximately 2.1 A and can tolerate peak currents up to 6 A. Since this board is a carrier for the DRV8874, we recommend careful reading of the DRV8874 datasheet. The board ships populated with all of its SMD components, including the DRV8874.
