Abstract
A sensing and control circuit for power line shorts works especially well for sensor or actuator devices controlled through a microcontroller. A power control circuit is placed between a pin of a programmable microcontroller and a sensor or actuator device to act as a short detector and switch to control power to the device. A capacitor in the power control circuit is charged and sensed by a single pin of the microcontroller to regulate a transistor which switches power to the device.
