Digital LED Solution for Automotive

Next-generation viable in-car lighting

The next generation of in-car ambient lighting will typically comprise of 10 to 30 LEDs mounted on a flexible light strip. Each 'group' consists of one red, green and blue LED to form a 'pixel', which is then intelligently controlled by the ISELED smart RGB LED driver, effectively replacing the present cumbersome and costly work-around utilizing multiple microcontrollers and a slow LIN bus.

Until now, ISELED smart LED drivers have only been available for purchase pre-integrated in an LED module. The INLC100Q16 is the first standalone driver available that enables manufacturers to custom design their own choice of external LED strips.

Several LED-related solutions for the automotive market are continuously being developed under the umbrella of the open ISELED Alliance. The current partners of the ISELED Alliance include Inova Semiconductors, Dominant Opto, Lucie Labs, NXP, TE Connectivity, the University of Pforzheim, Valeo, OLSA, Melexis, OSRAM and Microchip.
