Abstract
An electric circuit comprising at least one MOS switching transistor disposed on the side of high potential and a switchable charge pump supporting the switching-on phase of the MOS switching transistor at a pumping voltage output thereof with a pumping voltage higher than the potential of the supply voltage on the side of high potential at a pumping voltage output thereof. A control gate of the MOS switching transistor is connectable by means of a controllable switch to a high-potential-side supply voltage terminal or to the pumping voltage output depending on whether a predetermined threshold value on the switching-on ascending edge of the MOS switching transistor signal is exceeded or not.
