Abstract: Some embodiments relate to an electrostatic discharge (ESD) protection device to protect a circuit from an ESD event. The ESD protection device includes first and second trigger elements. Upon detecting an ESD pulse, the first trigger element provides a first trigger signal having a first pulse length.
