Bei einem Leistungs-MOSFET (1) mit sourceseitiger Last (2) ist eine Strombegrenzung über die Erfassung der Spannung zwischen Gate und Masse nicht möglich. Zwischen Gate und Source ist daher die Drain-Sourcestrecke eines zweiten FET (5) eingeschaltet, der eine definierte Einsatzspannung hat. Der Gate ...
