Abstract: A semiconductor device includes an internal circuit connected to at least one pad. A first inductor element is connected between the at least one pad and the internal circuit, a second inductor element coupled to the first inductor element and generating an induced voltage due to an overcurrent flowing in the first inductor element. An event detection circuit includes a monitoring element connected to the second inductor element. The monitoring element is configured to generate an event detection signal by sensing changes in properties of the monitoring element caused by at least one of the induced voltages generated in the second inductor element and a current flowing in the second inductor element. The internal circuit supplies an operating voltage to the event detection circuit, and determines whether an event causing the overcurrent has occurred by receiving the event detection signal from the event detection circuit.
