Abstract: High voltage clamps with transient activation and activation release control are provided herein. In certain configurations, an integrated circuit (IC) includes a clamp electrically connected between a first node and a second node and having a control input. The IC further includes a first resistor-capacitor (RC) circuit that activates a detection signal in response to detecting a transient overstress event between the first node and the second node, an active feedback circuit that provides feedback from the first node to the control input of the clamp in response to activation of the detection signal, a second RC circuit that activates a shutdown signal after detecting passage of the transient overstress event based on low pass filtering a voltage difference between the first node and the second node, and a clamp shutdown circuit that turns off the clamp via the control input in response to activation of the shutdown signal.

Abstract: High voltage clamps with active activation and activation-release control are provided herein. In certain configurations, a clamp can have scalable operating clamping voltage level and can be used to protect the electrical circuit connected to a power supply of a semiconductor chip from damage from an overstress event, such as electrostatic discharge (ESD) events. The pins of the power supply are actively monitored to detect when an overstress event is present, and the clamp is turned-on in response to detecting the overstress event. A timer is used to shut down the clamp after a time delay from detecting the overstress event, thereby providing a false detection shutdown mechanism that prevents the protection clamp from getting falsely activated and remain in the on-state during normal circuit operation.

Each of the first and second EOS protection switches includes a first semiconductor-controlled rectifier (SCR) and a second SCR and a first diode having a cathode electrically connected to an anode of the first SCR and a second diode having a cathode electrically connected to an anode of the second SCR. The first EOS protection device is configured to be activated in response to an EOS condition that causes a first bias between the first and second terminals, and wherein the second EOS protection device is configured to be activated in response to an EOS condition that causes a second bias between the first and second terminals.

Abstract: Low leakage bidirectional clamps and methods of forming the same are provided. In certain configurations, a bidirectional clamp includes a first p-well region, a second p-well region, and an n-well region positioned between the first and second p-wells regions. The bidirectional clamp further includes two or more oxide regions over the n-well region, and one or more n-type active (N+) dummy blocking current regions are positioned between the oxide regions. The one or more N+ dummy leakage current blocking regions interrupt an electrical path from the first p-type well region to the second p-type well region along interfaces between the n-well region and the oxide regions. Thus, even when charge accumulates at the interfaces due to extended high voltage, e.g., >60V, and/or high temperature operation (e.g., >125° C.), the N+ dummy leakage current blocking regions inhibit charge trapping-induced leakage current.
