Abstract
The disclosure relates to an electronic control unit (ECU) for a vehicle. The ECU includes a 12V-domain controlling an electric load supplied with a first supply voltage and a 48V-domain controlling an electric load supplied with a second supply voltage. Both domains are arranged on a single printed circuit board (PCB) and are galvanically isolated from each other and connected with each other by a galvanically isolated data interface that transfers data between the domains according to a half-duplex or a full-duplex communication protocol. The 48V-domain includes a 48V-microcontroller and a 48V-power supply supplying the 48V-microcontroller, where the 48V-power supply is powered by the first supply voltage from the 12V-domain via a galvanically isolated supply interface.
