    摘要: An electronic device having an LV-well element trigger structure that reduces the effective snapback trigger voltage in MOS drivers or ESD protection devices. A reduced triggering voltage facilitates multi-finger turn-on and thus uniform current flow and/or helps to avoid competitive triggering issues.

    摘要: An apparatus having an inter-domain electrostatic discharge (ESD) protection circuit for protection of an integrated circuit (IC) with multiple power domains. The protection circuit in response to an ESD event provides an ESD protection between different power domains. Specifically, the protection circuit comprises at least one clamp coupled to one power domain, which conducts current during an ESD event to provide extra current in the interface line between the two different power domains. This extra current also in turn increases the voltage over the impedance element on the interface line, thus improving the design margins for the ESD protection and providing a better ESD protection capability for IC products.

    摘要: Apparatus for ESD circuit protection including a trigger subcircuit coupled between a first voltage reference potential and second voltage reference potential and an ESD shunt subcircuit coupled to the trigger subcircuit between a circuit device to be ESD-protected and the second voltage reference potential. The ESD shunt subcircuit is adapted for connection by a pad of an integrated circuit (IC) connection. The ESD shunt subcircuit is a silicon-controlled rectifier (SCR) that has an anode connected to the circuit device to be ESD-protected and a cathode connected to the second voltage reference potential. The trigger subcircuit is either an RC-triggered PMOS or a GGNMOS and series connected resistor.

    摘要: The present invention provides an improvement on ESD protection circuitry by controlling the trigger circuit to prevent the unwanted triggering of the device. The circuitry includes an ESD clamp with a trigger circuit coupled to the clamp. Both the clamp and the trigger circuit are coupled to a first reference potential. The circuitry also includes a control line coupled to the trigger circuit. The control line is coupled to a second reference potential to further control the behavior of the trigger circuit such that when the power is supplied to the second reference potential, the control line disables the trigger circuit, and when power is not supplied to the second reference potential, the control line enables the trigger circuit.
