摘要： An electrostatic discharge protection which is electrically coupled with an interface terminal and a devices area, at least include a first bipolar junction transistor, a second bipolar junction transistor, a first MOS transistor, and a second MOS transistor. Both bipolar junction transistors forms the well-known silicon controlled rectifier, first MOS transistor locates between interface terminal and second bipolar junction transistor and second MOS transistor locates between emitter of second bipolar junction transistor and ground point, and gates of both MOS transistor electrically coupled with voltage base point whose voltage is equal to work voltage of devices area. While devices area is turned off, silicon controlled rectifier would be latch-up and provides function of electrostatic discharge protection. While devices area is turned on, second MOS transistor also is turned on so that part of current flows into ground point but not flows into second bipolar junction transistor. Thus, positive feedback between two bipolar junction transistors is reduced and then latch-up is eliminated.

摘要： The present invention provides a PMSCR (bridging modified lateral modified silicon controlled rectifier having first conductivity type) with a guard ring controlled circuit. The present invention utilizes controlled circuit such as switch to control functionally of guard ring of PMSCR. In normal operation, the switch is of low impedance such that the guard ring is short to anode and collects electrons to enhance the power-zapping immunity. Furthermore, during the ESD (electrostatic discharge) event, the switch is of high impedance such that the guard ring is non-functional. Thus, the PMSCR with guard ring control circuit can enhance both the ESD performance and the power-zapping immunity in the application of the HV (high voltage) pad.

摘要翻译： 本发明提供了具有保护环控制电路的PMSCR（具有第一导电类型的桥接修改的侧向修改的可控硅整流器）。 本发明利用诸如开关的控制电路来控制PMSCR保护环的功能。 在正常工作中，开关具有低阻抗，使得保护环与阳极短路并收集电子以提高功率跳跃抗扰度。 此外，在ESD（静电放电）事件期间，开关具有高阻抗，使得保护环不起作用。 因此，具有保护环控制电路的PMSCR可以在HV（高电压）焊盘的应用中增强ESD性能和功率切换抗扰性。
