Abstract
This document discusses, among other things, a protection system and method configured to detect a parasitic impedance between first and second pins of a standard connector and to remove a current path between a power source and a supply pin of the standard connector if a low-impedance is detected, in certain examples, without adding a current sense resistance to a return path between a ground pin of the standard connector and the power source.
