Abstract

An electrostatic discharge protective circuit may comprise a low-pass filter and a high-pass filter to receive and filter signals of a supply line. Control logic may receive output signals of the low-pass and high-pass filters and may operate a gateable channel to shunt current of the supply line dependent on the output signals from the filters.
