Abstract

See full text

Systems, methods, techniques and apparatuses of power switch protection are disclosed. One exemplary embodiment is a protection system for a power switch comprising a resistor and a detection circuit. The resistor is coupled in series with a decoupling capacitor. The detection circuit is structured to receive a voltage of the resistor, determine a short circuit is occurring based on the received electrical characteristic, and transmit a fault trigger signal in response to determining the short circuit is occurring.
