Abstract
The present invention provides a method for actuating a transistor () having the following steps: (a) a first predetermined positive potential is applied to a first voltage supply node () in a latch circuit (), the voltage supply node () being coupled to a control connection on the transistor (); (b) a reference-ground potential is applied to a second voltage supply node () in the latch circuit (), the second voltage supply node () being connected to a source connection on the transistor (); (c) the latch circuit () is set to a predetermined state, which turns the transistor () on or off; (d) the potential at the second voltage supply node () is lowered; and (e) the potential at the first voltage supply node () is lowered if the potential difference between the first and second voltage supply nodes () exceeds a predetermined threshold value.
