Abstract
A trigger circuit coupled between an input-output pad and a core circuit and including an adjustment circuit and a protection circuit is provided. The adjustment circuit adjusts the voltage of the input-output pad to generate an output voltage. The protection circuit is coupled between the adjustment circuit and the core circuit and receives a system enable signal. In response to the system enable signal being disabled or an electrostatic discharge (ESD) event occurring on the input-output pad, the protection circuit disables the core circuit according to the output voltage. In response to the system enable signal being enabled, the protection circuit stops disabling the core circuit.
