Abstract
An electrostatic discharge (ESD) protection circuit including a detection circuit, a voltage-divider element, and a discharge element is provided. The detection circuit is coupled between a first power line and a second power line. In response to an ESD event, the detection circuit enables a turn-on signal. The voltage-divider element is coupled between the first power line and a third power line and receives the turn-on signal. The discharge element is coupled between the second and third power lines. In response to the turn-on signal being enabled, the first discharge element discharges an ESD current.
