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.

Circuit protection device

A chip fuse includes a plurality of parallel fusible link layers disposed between a corresponding plurality of insulating glass layers deposited on a substrate and laminated together. The fusible link layers are interconnected between the glass layers without the need for vias. A first of the plurality of fusible link layers extends beyond a cover disposed over the chip fuse and one of the glass layers to form a first electrical terminal connection. Another of the plurality of the fusible link layers also extends beyond the cover and another of the glass layers to form a second electrical terminal connection.
