Abstract: A semiconductor circuit comprises a control circuit (14) with a load (RL) between a supply voltage and a controllable timing semiconductor element (2) to time switching of the load. The circuit is usable in a power supply network. A semiconductor circuit comprises a control circuit (14) with adjacent control signal and a controllable, integrated, self on- and off-switching semiconductor element. There is a switch (2) for timed switching of a load (RL) and two current sources (3,5), the second providing a status signal. A starting load device (11) provides energy for the control circuit and a monitoring device measures the voltage between the load connections and produces the status signal. An Independent claim is also included for a power supply network comprising the semiconductor device above.
