(57) Abstract :
A voltage clamp protection circuit to protect against overvoltage conditions where there is insufficient current to blow a fuse. The
voltage clamp protection circuit includes a voltage clamp and a thermal cutoff. The voltage clamp clamps any overvoltage to a
clamping voltage. If an overvoltage condition persists for too long the voltage clamp dissipates a sufficient amount of heat to activate
the thermal cutoff creating an open circuit that protects the rest of the circuit The voltage clamp protection circuit may be used in
combination with a variety of other protection circuits to provide increased protection.
