Abstract
An electrostatic discharge (ESD) protection apparatus includes: an ESD circuit, arranged to perform ESD protection, wherein the ESD circuit includes a first Field Effect Transistor (FET) arranged to release ESD energy; a detection circuit, arranged to perform detection to control the ESD protection apparatus to selectively operate in one of a normal mode and a discharge mode; and a logic circuit, arranged to withstand any oscillation due to resistance-inductance-capacitance (RLC) characteristics of the detection circuit. In the detection circuit, different subsets of a plurality of resistors are respectively combined with a portion of a first serial connection circuit, an entirety of the first serial connection circuit, and a second FET to form different serial connection circuits, to configure the second FET to approach a state of being completely turned off in the normal mode.
