Control circuit for a high-side semiconductor switch for switching a supply voltage

A control circuit for a high-side semiconductor switch for switching a positive supply voltage, said high-side semiconductor switch being connected between said supply voltage and a floating switching point, said control circuit comprising:

• a circuit portion for providing a drive voltage for said high-side semiconductor switch;
• a driver circuit portion (48) for driving said high-side semiconductor switch on the basis of said drive voltage, said circuit portion for providing said drive voltage and said driver circuit portion operating in relation to said floating switching point;
• an input circuit portion for receiving a control signal related to ground;
• and
• a level shift circuit portion that is connected between said input circuit portion and said driver circuit portion and configured to transform said control signal related to ground into a floating voltage level for said driver circuit portion;
• wherein said level shift circuit portion by comprises a degeneratively coupled control semiconductor switch and is coupled to a negative feedback circuit portion, said negative feedback circuit portion has comprising a first negative feedback element and a second negative feedback element that are configured such that, depending on an operating status of said high-side semiconductor switch, only one or both of said negative feedback elements are active as current negative feedback for said control semiconductor switch.
