Abstract
An electrostatic discharge (ESD) protection circuit is disclosed including at least a clamping device, a switching device, and a voltage limiter. The ESD protection circuit may include devices of different voltage domains. The switching device may be in series with the clamping device to block at least a portion of a voltage from dropping across the clamping device. The switching device may sustain higher maximum operating voltages than the clamping device.
