摘要：A circuit arrangement comprises a first terminal for connection to a voltagesource, a second terminal for connection to a first current sink and a third terminal for

supplying a potential signal. A first diode string can be connected to the voltage sourceon the anode side and to the first current sink on the cathode side. The third terminal canbe coupled to the cathode side of the first diode string by a resistor. An adjustablereference current sink is coupled to the third terminal, for generating a referencecurrent, and comparison unit coupled to the third terminal on the input side for providinga short-circuit detection signal in dependence on a difference between the potentialsignal and an adjustable reference voltage. The potential signal can be supplied independence on a first short-circuit voltage across the first diode string and independence on the reference current.
