Abstract
A protection device includes a substrate capable of suppressing electromagnetic fields, with a channel formed therein, a current dependent circuit interrupter disposed inside the channel, and voltage management circuitry coupled to the substrate. The voltage management circuitry is electrically coupled to the current dependent circuit interrupter so as to form a crowbar circuit in the presence of overvoltage or undervoltage conditions as determined according to a reference voltage.
