MP6550 Single Brushed DC Motor Driver Carrier
This tiny breakout board for the MPS MP6550 motor driver offers a wide operating voltage range of 1.8 V to 22 V and can deliver a continuous 1.7 A (2.5 A peak) to a single brushed DC motor. The MP6550 has built-in current sensing and current limiting as well as protection against under-voltage, over-current, and over-temperature conditions. The carrier board also adds reverse-voltage protection up to 20 V.

Notes:
- 1
- Without included hardware.
- 2
- Default current limit determined by on-board configuration resistor.
- 3
- Determined by on-board configuration resistor.
- 4
- The MP6550 datasheet specifies 5 V as the absolute maximum voltage on any control input, but we do not recommend operation with a nominally 5 V logic voltage.
- 5
- Note: Reverse voltage protection only works up to 20 V.
