Abstract:
A current limiting circuit for a motor controller includes a comparator. The comparator has a sensed current input, a current threshold input, and an overcurrent protection trip output. A variable resistance current threshold circuit is connected to the current threshold input. A first controller is connected to the variable resistance current threshold circuit via a plurality of connections. The first controller is configured to control a voltage output of the variable resistance current threshold circuit.
