Abstract
An apparatus generally having a first circuit, a second circuit and a third circuit is disclosed. The first circuit may be configured to selectively switch a bonding pad to (i) a first rail of a power source and (ii) a discharge rail in response to an electrostatic discharge. The second circuit is generally configured to clamp the electrostatic discharge between the discharge rail and the first rail. The third circuit may be configured to bias the discharge rail to a second rail of the power source.
