An ESD protection circuit including a discharge device, a first detection circuit, and a second detection circuit. The discharge device provides a discharge path between a first power rail and a second power rail when the discharge device is activated. The discharge device stops providing the discharge path when the discharge device is de-activated. The first detection circuit is coupled between the first and the second power rails. The first detection circuit activates the discharge device when an ESD event occurs in the first power rail. The second detection circuit de-activates the discharge device when the ESD event does not occur in the first power rail.

A transient detection circuit coupled between a first power line and a second power line and including a first control unit, a setting unit, and a voltage regulation unit. The first control unit generates a first control signal. The first control signal is at a first level when an electrostatic discharge (ESD) event occurs. The first control signal is at a second level when the ESD event does not occur. The setting unit sets a first node. The first node is set at the second level when the first control signal is at the first level. The voltage regulation unit regulates the first node. The voltage regulation unit regulates the level of the first node at the second level when the first control signal is at the second level.

A transient detection circuit including a detecting unit, a setting unit, and a memory unit. The transient detection circuit provides an information signal to an external instrument when an electrostatic discharge (ESD) event occurs. The detecting unit is coupled between a first power line and a second power line for detecting the ESD event. The setting unit sets a level of a first node according to the detection result. The memory unit controls the information signal according to the level of the first node. The information signal is at a first level when the ESD event occurs in the first power line.

A digital converter including a first adjustment unit and a first transient detection unit. The first adjustment unit adjusts amplitude of an electrostatic discharge (ESD) pulse to generate a first adjustment signal when an ESD event occurs in a first power line and a second power line is at a complementary level. The first transient detection unit generates a first digital code according to the first adjustment signal.
