Shown here is an example of a LIN RGB module. The main components are the 8-pin IS32LT3183A LIN driver and packaged RGB LEDs. Other discrete components are protection diodes, noise filter capacitors and voltage drop resistors. The R1, R2, and R3 resistors are required since the LED’s common anode is connected directly to the 12 V supply. Not having the voltage drop resistors will cause the IS32LT3183A’s current sinks to overheat due to the V*I thermal increase. There are two four pin connectors; Connector 1 is for power and LIN bus while Connector 2 is for connecting external LEDs. Remove R1, R2 and R3 when using external LEDs. Also, note there are no crystals or ceramic resonators as required by the CAN bus because there is no need for time synchronization since LIN has no bus arbitration.
