Compact control for lamps in a motor vehicle

A method for manufacturing a device for driving an LED lighting device,

• wherein the device is provided with:
• an input designed as a data interface for connection to a communication data bus,
• an output with at least one terminal for at least one LED lamp, which comprises an LED or a series circuit of LEDs or a group of differently colored LEDs or a series circuit of groups of respectively differently colored LEDs,
• a microcontroller,
• one or more LED driver circuits, wherein an LED driver circuit is associated with each terminal of the output for an LED lamp,
• wherein the data interface, the microcontroller, and the LED driver circuit or the LED driver circuits comprise electronic and/or electrical circuit elements, and
• a semiconductor substrate, the method comprising:
• integrating the circuit elements of the data interface, the microcontroller and the LED driver circuit or the LED driver circuits in the semiconductor substrate using a semiconductor technology for manufacturing integrated circuits with a smallest possible structure size predetermined by the semiconductor technology, and
• determining the semiconductor technology used by what minimum structure size is permissible for the circuit elements of the data interface and/or the LED driver circuit and/or the LED driver circuits in order to ensure their functionality,
• wherein the data interface and/or the at least one LED driver circuit comprise circuit elements, the structure size of which is equal to the smallest possible structure size determined by the semiconductor technology, and
• wherein the microcontroller comprises circuit elements of which those with the smallest structure size have a structure size equal to the structure size of the circuit elements of the data interface and/or the at least one LED driver circuit with the smallest possible structure size determined by the semiconductor technology.
