Abstract:
A method and circuit are described for detecting an overvoltage condition and using the detection of the overvoltage condition to protect a circuit or component from the overvoltage condition. In one embodiment, an overvoltage protection circuit is used to detect an overvoltage condition on pin driver electronics, the detection of which is powered by the overvoltage condition itself, thus eliminating the need to provide overvoltage protection circuitry that requires power supplies with voltages greater than the pin electronics the overvoltage protection circuit is meant to protect.
