An electronic circuit (100) includes a first circuit (140) having an output and operable to give a warning but that has a sensitivity to an electrostatic discharge (ESD) event, a second circuit (120) that is operationally at least sometimes coupled with the output of said first circuit (140), whereby subject to some of the sensitivity, and a third circuit (240) interposed between said first circuit (140) and said second circuit (120) and operable to filter out at least one instance of an unnecessary warning so as to reduce the sensitivity to the ESD event.
