    摘要: An ESD protection circuit (81) and a method for providing ESD protection is provided. In some embodiments, an N-channel transistor (24), which can be ESD damaged, is selectively turned on and made conducting. The purpose of turning on the N-channel transistor (24) is to maximize the Vt1 of the N-channel transistor (24). Vt1 is the drain-to-source voltage point at which the parasitic bipolar action of the N-channel transistor (24) first occurs. In some embodiments, the ESD protection circuit (81) includes a diode (64) which provides an additional current path from the I/O pad 31 to a first power supply node (76).

    摘要: A rail clamp circuit (100) includes first and second power supply voltage rails, a multiple independent gate field effect transistor (MIGFET) (128), and an ESD event detector circuit (138). The MIGFET (128) has a source/drain path coupled between the first (112) and second (114) power supply voltage rails, and first and second gates. The ESD event detector circuit (138) is coupled between the first (112) and second (114) power supply voltage rails, and has first and second output terminals respectively coupled to the first and second gates of the MIGFET. In response to an electrostatic discharge (ESD) event between the first (112) and second (114) power supply voltage rails, the ESD event detector circuit (138) provides a voltage to the second gate to lower an absolute threshold voltage of the MIGFET (128) while providing a voltage to the first gate above the absolute threshold voltage so lowered, thereby making the MIGFET (128) conductive with relatively high conductivity.
