Electrostatic discharge protection circuit and electrostatic discharge protection method
An ESD protection circuit and method for its use are provided. The circuit comprising: a discharge path formed by first and second NMOS transistors which are sequentially connected between a ground and a power supply; an ESD event detection unit; first and second drive units respectively connected between an output of the ESD event detection unit and a gate of the first transistor and between the output of the ESD event detection unit and a gate of the second transistor. The first and second drive units respectively cause the first and second transistors to be turned on during an ESD event and to be turned off when there is no ESD event.
