Abstract

A device and related method for supplying power to a vehicle-control-unit, including: a first-connection (FC) for a first power-supply-path (PSP), a second-connection (SC) for a second PSP and a neutral-point for connecting the first- and second-PSPs; a first-switch having a first-contact connected to the FC and a second-contact connected to the neutral-point, and a second-switch having a first-contact connected to the SC and a second-contact connected to the neutral-point; first and second-measuring-contacts for capturing first- and second-measured-values representing voltage-potentials of the first-PSP and the second-PSP; a control-device to keep one of the switches open and the other of the switches closed in response to a test-state; and a monitoring-device providing a monitoring-signal using the first and second measured-values for the test-state.
