  • Patent number: 11063583
    Abstract: A multi-sense circuit includes a transistor circuit having sense nodes and a gate node, a peak detector having inputs coupled to the sense nodes of the transistor circuit and an output, and a control circuit having a gate control node coupled to the gate node of the transistor circuit and an overcurrent protection node coupled to the output of the peak detector.
    Type: Grant

    Date of Patent: July 13, 2021
    Assignee: Infineon Technologies AG
    Inventors: Marcus Nuebling, Tom Roewe
  • Patent number: 10916931
    Abstract: In accordance with an embodiment, a method includes: monitoring a temperature difference between two double-side cooled (DSC) power modules of a plurality of DSC power modules arranged in stacks of DSC power modules; comparing the temperature difference with a first temperature threshold; detecting a cooling pipe system blockage when the temperature difference is above the first temperature threshold; and after detecting the cooling pipe system blockage, disabling gate driver circuits coupled to the plurality of DSC power modules or operating the DSC power modules in a low-power mode. Each stack includes a plurality of DSC power modules. Each DSC power module has a top surface and a bottom surface, which are each thermally coupled with one or more cooling channels of a cooling pipe system. The two DSC power modules are thermally coupled with a same cooling channel of the one or more cooling channels.

  • Patent number: 9035687
    Abstract: A circuit is described that includes a switch, a switchable clamping element coupled to the switch, and a driver configured to control the switch based at least in part on a driver control signal. The driver is further configured to enable or disable the switchable clamping element. The switchable clamping element is configured to clamp a voltage across the switch when the switchable clamping element is enabled by the driver and when the voltage across the switch or a current at the switch satisfies a threshold for activating the switchable clamping element.
