Abstract
The present disclosure provides an electrostatic discharge (ESD) protection circuit and configuration method thereof. The ESD protection circuit includes first and second power supply terminals, first and second detection units, a control unit, a clamping unit, and a voltage-dividing output node defined between the first and second power supply terminals. The first detection unit detects an electrostatic signal, based on a signal between the first power supply terminal and the voltage-dividing output node, and outputs a first signal. Likewise, the second detection unit outputs a second signal. The control unit is configured to be driven by the first signal to convert into a first discharge control signal and by the second signal to convert into a second discharge control signal. The clamping unit is configured to receive the first and second discharge control signals to discharge an electrostatic current between the first and the second power supply terminals.
