ABSTRACT:
A control circuit for an MOS semiconductor component having gate and source terminals has a load connected in series with the source terminal. A voltage source at fluctuating potential has first and second terminals. A first controllable semiconductor switch has a control input and is connected between the first terminal of the voltage source and the gate terminal of the MOS semiconductor component. The second terminal of the voltage source is connected to the source terminal of the MOS semiconductor component. A second switch is controllable by an input signal and has first and second load terminals. A line is connected to a fixed potential and to the first load terminal of the second switch. The second load terminal of the second switch is switched from a first to a second potential as a function of the input signal. The first and second potentials are between potentials of the first and second terminals of the voltage source. The first and second potentials are applied to the control input of the first switch for making the first switch conducting whenever an input signal is applied.
