The apparatus for supplying at least one consumer with electrical energy or for providing electrical power for at least one consumer from an on-board motor vehicle electrical system is provided with a control circuit (10), which is designed as an IC and has an input (1) by means of which electrical energy can be supplied to the control circuit (10) from the on-board motor vehicle electrical system, and having at least a first output (3) and a second output (4), wherein a consumer (11) can be supplied with electrical energy from the on-board motor vehicle electrical system by the control circuit (10) by means of each of said two outputs (3, 4), or the control circuit (10) can provide electrical power for a consumer (11) by means of said outputs, at least one external resistor (R3, R4, R8), which is arranged outside the IC, for emitting potential lost electrical power outside the IC, wherein firstly the external resistor (R3, R4, R8) is connected to the second output (4) of the control circuit (10), and secondly the consumer (11) can be connected to the external resistor (R3, R4, R8). The setpoint value for the electrical power of the consumer (11), which electrical power can be controlled by the control circuit (10), can be prespecified. Dividing the electrical energy for the consumer (11) or the electrical power which is provided for said consumer between the at least two outputs (R3, R4) of the control circuit (10) can be controlled by said control circuit depending on at least one division parameter (Vp). Said division parameter can be supplied to the control circuit (10) or determined in the control circuit (10). |
