Zusammenfassung:An ESD detection circuit for detecting a level of an ESD voltage on a power rail is provided. The ESD detection circuit includes a resistive component, a diode unit, and a controller. The resistive component is coupled between a detection node and a ground node corresponding to the power rail. The diode unit is coupled between the power rail and the detection node in a forward direction toward the power rail. The controller, coupled to the detection node, is used for determining the level of the ESD voltage based on the voltage of the detection node and the breakdown voltage of the diode unit.
