Abstract
A circuit protection device includes a conductive layer which is connected to first and second terminals. A spring is electrically connected to the first and second terminals. When an over-voltage or over-temperature condition occurs within a charging circuit, one or more heat generating resistive elements melts material associated with one or more of the ends of the spring thereby releasing the spring to create an open circuit.
