  • Protective circuit for a field-effect transistor
    Patent number: 11456588
    Abstract: A protective circuit includes a first field-effect transistor having a first drain terminal, a first source terminal and a first gate terminal, a control device by which an electrical first voltage between the first drain terminal and the first source terminal can be determined, and a first temperature sensor by which a first temperature of the first field-effect transistor can be detected, wherein a first resistance of the first field effect transistor and an electrical first current conducted via the first field-effect transistor can be determined by the control device based on the first temperature.
    Type: Grant
