Abstract:
1. An electrical over-current protection device comprising: a component package having integrated therein first and second pairs of package terminals, wherein the first pair is electrically isolated from the second pair, a resettable thermally sensitive over-current protector coupled to the first pair of terminals and having a low resistance state and a high resistance state, wherein the over-current protector is a positive temperature coefficient (PTC) over-current protector element that changes from the low resistance state to the high resistance state in response to sufficiently high current passing through the first pair of terminals, wherein the first and second pairs of terminals remain electrically isolated from each other during both the low resistance state and the high resistance state, and an electrical heating element coupled to the second pair of terminals, wherein the PTC over-current protector element is larger than and entirely overlays the electrical heating element, and wherein the first pair of terminals, to which the PTC over-current protector are coupled, are located outward of the second pair of terminals.
