  • Patent number: 10411005
    Abstract: The present disclosure describes exemplary configurations and arrangements for various intelligent diodes. The intelligent diodes of the present disclosure can be implemented as part of electrostatic discharge protection circuitry to protect other electronic circuitry from the flow of electricity caused by electrostatic discharge events. The electrostatic discharge protection circuitry dissipates one or more unwanted transient signals which result from the electrostatic discharge event. In some situations, some carrier electrons and/or carrier holes can flow from intelligent diodes of the present disclosure into a semiconductor substrate. The exemplary configurations and arrangements described herein include various regions designed collect these carrier electrons and/or carrier holes to reduce the likelihood these carrier electrons and/or carrier holes cause latch-up of the other electronic circuitry.

  • Patent number: 10262990
    Abstract: A robust electrostatic (ESD) protection device is provided. In one example, the ESD protection device is configured to accommodate three nodes. When used with a differential signal device, the first and second nodes may be coupled with the differential signal device's BP and BM signal lines, respectively, and the third node may be coupled to a voltage source. This allows for a single ESD protection device to be used to protect the signal lines of the differential signal device, thus providing significant substrate area savings as compared to the conventional means of using three dual-node ESD protection devices to accomplish substantially the same protection mechanism. Moreover, the ESD protection device may be structurally designed to handle high voltage ESD events, as required by the FlexRay standard.
