SURGE-PROTECTION CIRCUIT AND SURGE-PROTECTION METHOD

摘要

A surge-protection circuit for a chip is provided. The surge-protection circuit includes a detection element and a protection element. The detection element is embedded on the chip and arranged between a first terminal and a second terminal, and the detection element is utilized to detect whether an abrupt voltage variation occurs due to a surge or not and generate an enabling signal when the abrupt voltage variation occurs. The protection element is embedded on the chip and coupled to the detection element, and the protection element is utilized to adjust and reduce the abrupt voltage variation through bypassing high energy generated by the surge after receiving the enabling signal.
