Abstract

The present invention discloses an electrostatic discharge (ESD) protection circuit, including: a first terminal configured to receive a first voltage; a second terminal configured to receive a second voltage; a detection voltage generating circuit configured to provide a detection voltage according to the first voltage and the second voltage; a warning circuit configured to generate a control signal according to the detection voltage, in which the control signal indicates a normal condition when the detection voltage satisfies predetermined voltage setting, and the control signal indicates an abnormal condition when the detection voltage does not satisfy the predetermined voltage setting; and a protected circuit configured to carry out a self-protection operation when receiving the control signal indicating the abnormal condition.
