ABSTRACT:
An overvoltage protection circuit includes a shunt circuit adapted for connection to at least one circuit node to be protected from an overvoltage condition and a voltage generator coupled to the shunt circuit. The shunt circuit is selectively activated as a function of a control signal supplied to the shunt circuit. The voltage generator is operative to generate the control signal for activating the shunt circuit during the overvoltage condition. The control signal has a level which varies in a manner that at least partially changes offsets in activation threshold of the shunt circuit.
