<p>The arrangement has a semiconductor switching device (10) i.e. MOSFET transistor, with a load current output (12) for supplying load current (Il) to loads (V1, V2). A diagnosing current output (13) outputs diagnosing currents (Id-Id3) that are proportional to current flowing at the load current output, where a transmission factor is determined by a controller (100) based on the load current and a predefined current impulse (Ip). The controller outputs a load failure signal depending on comparison of the diagnosing currents with a threshold value and a diagnosing current threshold value. An independent claim is also included for a method for individually detecting failure of loads.</p> |
