Abstract
In a driver circuit for driving a half bridge, that has a high-side semiconductor switch and a low-side semiconductor switch that are connected in series between a first and a second supply potential terminal, a drive is allocated to each of the two semiconductor switches that are respectively switched inhibited or transmissive by the respective semiconductor switches according to the direction of a drive signal. A load can be connected between the high-side semiconductor switch and the low-side semiconductor switch. For an inhibited state of a semiconductor switch, its drive terminal is charged approximately with the potential of the second supply potential terminal in order to attain a negative bias voltage of the drive terminal opposite the source terminal.
