Abstract
The present invention discloses an electrostatic discharge protection circuit having false-trigger prevention mechanism. A RC circuit, including an input control terminal, is coupled between an electrostatic discharge input terminal for receiving an input power and a ground terminal. An inverter includes a P-type transistor circuit, including P-type transistors coupled between the electrostatic discharge input terminal and an output control terminal in series and having an internal connection terminal between two of the P-type transistors, and an N-type transistor, coupled between the output control terminal and the ground terminal. Gates of the P-type and N-type transistors are controlled by the input control terminal A switch transistor, having the gate controlled by the input control terminal, is coupled between the internal connection terminal and the ground terminal. A discharging transistor having the gate controlled by the output control terminal, is coupled between the electrostatic discharge input terminal and the ground terminal.
