ABSTRACT:
In the case of a circuit arrangement for monitoring the drain current of a metal oxide semiconductor field effect transistor T.sub.o whose effective transistor area is subdivided in order to provide an MOS measuring transistor T.sub.o ' and an MOS power transistor T.sub.o " the drain-source paths of the two MOS transistor sections T.sub.o', T.sub.o " are placed in different current loops SZ.sub.1, SZ.sub.b of a current mirror SP1, which is acted upon by a predeterminable reference current I.sub.ref. The current mirror SP1 has an output terminal E, which supplies a monitoring signal dependent on the difference between the drain-source voltages of the two MOS field effect transistors T.sub.o', T.sub.o ".
