    • The invention relates to a controller (1) for a multi-voltage on-board power supply (3) of a vehicle. The multi-voltage on-board power supply (3) has a first sub-network (31) which is designed to be operated by a first voltage supply source (311) with a first supply voltage and a second sub-network (32) which is designed to be operated by a second voltage supply source (321) with a second supply voltage. The controller (1) comprises the following: a transceiver (11) which is connected to ground via a first ground connection (316) of the first sub-network (31) and which is designed to communicate with a communication component (312) of the first sub-network (31); a control unit (12) which is connected to the same ground via a second ground connection (326) of the second sub-network (32) and which is designed to control a power component (322, 323) of the second sub-network (32); a transmission path (13) which couples a signal output (12-1) of the control unit (12) to a signal input (11-1) of the transceiver (11), wherein the transmission path (13) is designed to transmit a control signal provided by the control unit (12) at the signal output (12-1) to the signal input (11-1) of the transceiver (11); and a diode (131) which is arranged in the transmission path (13) and the cathode connection (131-1) of which is coupled to the second ground connection (326). Furthermore, a number of field effect transistors (132, 133) are provided, the number of field effect transistors (132, 133) coupling the transmission path (13) to the first voltage supply source (311) and/or to the second voltage supply source (321) on one side and to the first ground connection (321) and/or to the second ground connection (326) on the other side.
