可调电压隔离地对地ESD钳位电路
摘要：
本发明公开了一种可调电压隔离地对地ESD钳位电路。该钳位电路包括一双向可控硅整流器(SCR)和触发元件。该SCR耦合在第一和第二接地端之间。该触发元件也耦合在第一和第二接地端之间。此外，该触发元件配置成当该第一和第二接地端之间达到一期望的电压时提供一触发电流给该双向可控硅整流器。
摘要（英）：

A tunable voltage isolation ground to ground ESD clamp is provided. The clamp includes a dual-direction silicon controlled rectifier (SCR) and trigger elements. The SCR is coupled between first and second grounds. The trigger elements are also coupled between the first and second grounds. Moreover, the trigger elements are configured to provide a trigger current to the dual-direction silicon controlled rectifier when a desired voltage between the first and second grounds is reached.
