Abstract:
1. An electronic circuit connectable to a voltage source and a load, said electronic circuit comprising: a controllable load switch element that is arranged so that a supply voltage provided by the voltage source in a connected state is provided to the load when the load switch element is switched on and is not provided to the load when the load switch element is switched off; thus applying a pulsed voltage at the load; and a voltage detection circuitry that is coupled to the load and is arranged for controlling the load switch element in dependence on an average voltage derived by averaging the pulsed voltage applied at the load in a closed-loop manner; wherein the voltage detection circuit is arranged to be energized by the pulsed voltage applied at the load; and a switch-on circuitry coupled to the load switch element and arranged to switch on the load switch element for a determined period of time after a switch arranged between the switch-on circuitry and the voltage source is closed and wherein the switch-on circuitry comprises a series arrangement of a first capacitor and a third resistor and further a first switch element that has a control side that is coupled in between the first capacitor and the third resistor, and the first switch element is arranged between ground potential and a control side of the load switch element; and further comprising a switch-off circuitry that is coupled to the load switch element and is arranged to switch off the load switch element after the switch is opened.
