Zusammenfassung:The invention relates to a method and a control circuit for controlling a power MOS transistor, which has a control terminal and a load path and whose load path is connected in series with a load between voltage supply terminals, between which a power supply voltage is imposed so that a load voltage is imposed across the load and a load path voltage is imposed across the load path of the power MOS transistor. According to the invention, during a switching process when the power MOS transistor changes from a first switching state to a second switching state, there is generated a control current for the control terminal, which is dependent on the power supply voltage and on at least the load path voltage or the load voltage.
