Electrical over-current protection device
An electrical component package has integrated therein first and second pairs of electrodes, wherein the first pair of electrodes are electrically isolated from the second pair of electrodes. A thermally sensitive positive temperature coefficient (PTC) conductive element abuts the first pair of terminals. Also integrated in the package is an electrical heating element that abuts the second pair of terminals, and receives a drive current for generating heat that is transferred to trip the PTC conductive element. Other embodiments are also described and claimed.
