Abstract

See full text

An ESD protection circuit, which is coupled between either an I/O pad or a power pad and a ground terminal, includes a non-snapback device and a snapback device. When the voltage across the non-snapback device is not less than the non-snapback trigger voltage, the non-snapback device is turned on. When the voltage across the snapback device is not less than the snapback trigger voltage, the snapback device is turned on, and the voltage across the snapback device is held at the snapback holding voltage, in which the snapback holding voltage is less than the snapback trigger voltage. The non-snapback device and the snapback device are cascaded.
