Patents by Inventor Severin Kampl

Severin Kampl has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11451138
    Abstract: Driver circuits are disclosed having a high-side switch and a low-side switch. A pre-charging circuit is provided to pre-charge the low-side switch. In other implementations, methods are disclosed which involve precharging a low-side switch.
    Type: Grant
    Filed: April 16, 2018
    Date of Patent: September 20, 2022
    Assignee: Infineon Technologies Austria AG
    Inventors: Eslam Ramadan Mohamed Alfawy, Severin Kampl, Uwe Kirchner
  • Patent number: 10326441
    Abstract: A semiconductor assembly includes a first FET having gate, source and drain terminals, a switching device being configured to electrically short a gate-source capacitance of the first FET responsive to a control signal, a first gate lead, a second gate lead, a drain lead, and a source lead. The first and second gate leads, the drain lead, and the source lead form externally accessible terminals of the semiconductor assembly. A reverse blocking rating of the switching device is less than a reverse blocking rating of the first FET. A gate of the first FET is directly electrically connected to the first gate lead. A gate of the switching device is directly electrically connected to the second gate lead. The first FET and the switching device are the only active semiconductor devices connected between the first gate lead, the second gate lead, the drain lead, and the source lead.
