PURPOSE: An ESD protection circuit is provided to remove introduced ESD rapidly by effectively increasing the driving voltage of an ESD protection circuit using a NAND gate and a PMOS transistor. CONSTITUTION: A RC trigger(120) is formed between a current voltage node and a ground voltage node. An ESD discharge unit(160) grounds the ESD introduced in the current voltage node with the ground voltage node. An ESD driving voltage generator(140) generates the driving voltage of the ESD discharge unit.
