    摘要: The invention relates to an ESD protection with ability to enhance trigger-on speed of a low voltage Triggered PNP (LVTPNP) unit for protecting internal circuits of an integrated circuit from attack of an ESD stress. The ESD protection unit incorporates either detection circuit or power clamp circuit to efficiently trigger on a trigger node as a heavily doped region of LVTPNP devices among an I/O pad, a VDD pin and a VSS pin. As soon as the trigger node of each LVTPNP device receives a trigger signal from either the ESD detection circuit or power clamp circuit, the threshold voltage of the LVTPNP devices are capable of being therefore reduced to enhance trigger-on speed of the LVTPNP devices that discharge ESD current.
