An automotive electric auxiliary device includes an electronic high-voltage motor which is driven by an electronic high voltage power circuit, an electronic low-voltage control circuit which is galvanically isolated from the electronic high-voltage power circuit, and a wake-up unit which wakes-up the electronic high-voltage power circuit. The wake-up unit includes a low-voltage wake-up input port which receives a single wake-up flank, and an inductive coupling element which inductively transmits the single wake-up flank to a releasable latch unit. The releasable latch unit transforms the single wake-up flank to a set constant high-voltage activity signal level for indicating a non-sleeping mode to the electronic high-voltage power circuit.
