Abstract
A circuit protection device includes an overvoltage monitor circuit that is operable to monitor a power supply circuit to detect an overvoltage condition on the power supply circuit and to change a state of an overvoltage output responsive to the overvoltage condition on the power supply circuit. A bi-directional switch is operable to interrupt or limit current flow though the power supply circuit responsive to the change in the state of the overvoltage output. A bi-directional voltage limiter is connected across output terminals of the circuit protection device and is operable to limit an overvoltage to a predefined voltage limit.
