Abstract
An electrostatic discharge circuit may include a control voltage generation circuit, an electrostatic detection circuit, a driving control circuit and a discharge driving circuit. The control voltage generation circuit may generate first to third control voltages through a division operation on a supply voltage. The electrostatic detection circuit may set a first setup voltage based on the first control voltage, and detect static electricity transferred through the first setup voltage. The driving control circuit may set a second setup voltage based on the second control voltage, and generate a driving control signal. The discharge driving circuit may set a third setup voltage based on the third control voltage, and perform a discharge operation on static electricity.
