Device for controlling a field effect transistor

A device for LED actuation corresponding to a control signal present at a control line, the device comprising:

• at least one field-effect transistor (FET) for bypassing at least one respective light-emitting diode, said at least one field-effect transistor having a gate connection, a source connection and a drain connection and being an N-channel FET with a floating source potential with respect to the control line;
• at least one driver circuit including a current mirror having an input side and an output side for transmitting a current flowing on said input side to said output side, said input and output sides being connected to a supply voltage;
• said current mirror including a transistor pair having an input-side transistor and an output-side transistor with base connections connected to one another and to a collector connection of said input-side transistor;
• a level converter formed by a current sink and connecting said input side of said current mirror to the control line in order to impress a current being dependent on a voltage of the control signal;
• said output side of said current mirror being connected to the gate connection and to the source connection of said at least one field-effect transistor;
• and
• a gate resistor connected between the gate connection and the source connection of said at least one FET.
