Abstract
A circuit arrangement for overload protection, particularly for an evaluation electronics unit for child-seat detection in a vehicle, has first and second input connections for an input voltage signal, and first and second output connections for an output voltage signal. The first input connection and the first output connection are connected to one another by means of a first circuit path; and the source/drain path of a first field-effect transistor is included in a second circuit path from the second input connection to the second output connection, to block the second circuit path if an overvoltage is present. The source/drain path of a second field-effect transistor, is included in a third circuit path between the first circuit path and that connection of the first field-effect transistor which is coupled to the second input connection. The second field effect transistor completes the third circuit path when overvoltage is present between the first and the second input connection.
