DRV8801 Single Brushed DC Motor Driver Carrier
Texas Instruments’ DRV8801 is a tiny H-bridge motor driver IC that can be used for bidirectional control of a single brushed DC motor at 8V to 36V. It can supply up to about 1A continuously and can tolerate peak currents up to 2.8A for a few seconds, making it a good choice for small motors that run on a wide range of voltages. Since this board is a carrier for the DRV8801, we recommend careful reading of the DRV8801 datasheet (1MB pdf). The board ships populated with all of its SMD components, including the DRV8801.
For a more powerful driver with a similar operating voltage range, please consider our MAX14870 carrier. For a dual-channel driver with a similar operating voltage range, please consider our A4990 carrier or A4990 Arduino shield. For lower-voltage alternatives to the DRV8801, please consider our DRV8838 single-channel motor driver carrier and DRV8833 and DRV8835 dual motor driver carriers.
