Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Race… ...

By setting the R ISET resistor to 10 kΩ, the MP6522 can be set up to provide a current limit of 1.5 A. Figure 6 shows that the output turns on and off to limit the current through the dc motor. 6.

Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little ...
