ABSTRACT:
An electronic device includes an integrated circuit, a power interface, and an interface circuit connected between the integrated circuit and the power interface for protecting the integrated circuit from being damaged by electrostatic discharge. The interface circuit includes a current limit unit connected between the power interface and the integrated circuit for limiting an electrostatic discharge current and an electrostatic protection unit connected to a common node of the power interface and the current limit unit for clamping a voltage of the common node to a predetermined value. A related integrated circuit is also provided.
