  • Switching module
    Patent number: 10211643
    Abstract: A switching module comprising at least one current sense component.
    Type: Grant
    Filed: October 24, 2013
    Date of Patent: February 19, 2019
    Assignee: NXP USA, Inc.
    Inventors: Alexander Petrovich Soldatov, Vasily Alekseyevich Syngaevskiy, Gennady Mihaylovich Vydolob
  • Overcurrent protection device and method of operating a power switch
    Patent number: 9620951
    Abstract: An overcurrent protection device comprises a maximum-allowed-current unit and a power switch. The maximum-allowed-current unit determines a maximum allowed current in real-time. The maximum allowed current is determined at least partially on an instantaneous level of a load voltage. The load voltage is a voltage across a load to be powered. The power switch is connectable with a switch input to a voltage supply and with a switch output to the load, for providing power to said load. The power switch has a conductive state and a nonconductive state, and is arranged to assume the nonconductive state in response to an indication that a current through the power switch is exceeding the maximum allowed current. A method of operating a power switch is also described.

  • Circuit arrangement, lighting apparatus and method of crosstalk-compensated current sensing
    Patent number: 8952615
    Abstract: A circuit arrangement comprises a plurality of current channels located in different die areas of a shared circuit die, at least one of the plurality of current channels comprising a power device; at least one sense circuit connected to one or more of the different die areas and arranged to provide a sense current from sensing a current through a primary of the plurality of current channels comprising one of the different die areas. The at least one sense circuit comprises a compensation module arranged to provide a compensation current adapted to at least partly compensate a deviation of the sense current caused by crosstalk between the primary and one or more secondary of the plurality of current channels depending on one or more secondary currents flowing through the one or more secondary current channels; wherein the compensation module is arranged to provide the compensation current at least partly as a weighted sum of the one or more secondary currents.

  • OVERCURRENT PROTECTION DEVICE AND METHOD OF OPERATING A POWER SWITCH
    Publication number: 20130314832
    Abstract: An overcurrent protection device comprises a maximum-allowed-current unit and a power switch having a conductive state and a nonconductive state. The maximum-allowed-current unit determines a time-dependent maximum allowed current according to a supply voltage. The power switch assumes the nonconductive state in response to an indication that a current through the power switch is exceeding the maximum allowed current. A method of operating a power switch is also described.
