ABSTRACT:
A half-bridge circuit has first and second semiconductor switches, which have load paths connected in series and which are driven in dependence on an input signal that is applied to an input terminal. At least one first drive circuit is provided, which is connected to the control connection of the first semiconductor switch and which makes a first drive signal available. The first drive signal is dependent on the input signal and on a current from or to the control connection of the second semiconductor switch.
