  • Patent number: 10615595
    Abstract: An integrated circuit is provided in which a surge protector, protecting against modest over-voltage events which may contain a lot of energy, and an electrostatic discharge (ESD) protector, protecting against high voltage events that may contain only a little energy, are provided within the integrated circuit package. The two types of protectors may protect against different types of electrical events.

  • Patent number: 9871029
    Abstract: A bus driver is provided that can withstand over voltages being applied to its output terminal without the protection circuit detracting from the voltage swing that can be provided by the driver. The circuit arrangement also allows transistors having good on state resistance and large tolerance of drain-to-source voltages to be used.

  • Patent number: 9484739
    Abstract: A protection device is provided that exhibits a turn on time of order of one nanosecond or less. Such a device provides enhanced protection for integrated circuits against electrostatic discharge events. This in turn reduces the risk of device failure in use. The protection device can include a bipolar transistor structure connected between a node to be protected and a discharge path.

  • Patent number: 9356011
    Abstract: Junction-isolated blocking voltage devices and methods of forming the same are provided. In certain implementations, a blocking voltage device includes an anode terminal electrically connected to a first p-well, a cathode terminal electrically connected to a first n-well, a ground terminal electrically connected to a second p-well, and an n-type isolation layer for isolating the first p-well from a p-type substrate. The first p-well and the first n-well operate as a blocking diode. The blocking voltage device further includes a PNPN silicon controlled rectifier (SCR) associated with a P+ region formed in the first n-well, the first n-well, the first p-well, and an N+ region formed in the first p-well. Additionally, the blocking voltage device further includes an NPNPN bidirectional SCR associated with an N+ region formed in the first p-well, the first p-well, the n-type isolation layer, the second p-well, and an N+ region formed in the second p-well.

  • Patent number: 7453305
    Abstract: A voltage level shifting circuit (5) for shifting the common mode voltage of a differential signal to be within the working range of a differential input buffer circuit (3) comprises a first resistive voltage divider circuit (18) coupled between a first input terminal (10) and a voltage reference terminal (15) for receiving a voltage reference to which the common mode voltage of the level shifted differential signal is to be referenced, and a second resistive voltage divider circuit (18) coupled between a second input terminal (11) and the voltage reference terminal (15). The differential signal is applied to the first and second terminals (10,11), and the level shifted differential signal is produced on first and second output taps (17,19) of the first and second resistive voltage divider circuits (16,18) with the common mode of the level shifted differential signal referenced to the voltage reference applied to the voltage reference terminal (15).
