A circuit arrangement for detecting a load current through a load includes a main transistor, a sensing transistor through which a load current flows that is a measure of the load current flowing through the main transistor, a means of resistance which is connected in series with the load path of the sensing transistor, a current source which is connected to a node which is arranged between the sensing transistor and the means of resistance, and a detector which detects the load current flowing through the main transistor by measuring the voltage across the means of resistance.
