Abstract
An IC includes a pad, a current detection device connected to the pad and configured to generate monitoring information corresponding to an electrostatic discharge (ESD) event, and an internal circuit configured to receive the monitoring information from the current detection device, wherein the current detection device includes a current sensing circuit having a T-coil that is configured to generate an ESD current when the ESD event occurs and is further configured to generate an induced voltage corresponding to the ESD current, a plurality of detection circuits outputting a detection signal based on the induced voltage, and a monitoring circuit configured to receive the detection signal from each of the plurality of detection circuits and configured to generate the monitoring information, wherein the plurality of detection circuits have different sensitivities with respect to the induced voltage.
