Elmos showed at the CES in Las Vegas dynamic rear lights in an Audi A8 rear light demonstrator. The demonstrator features the new Elmos IC E522.95. This multichannel LED controller for exterior lighting with advanced network interface capabilities allows direct control of LED lamps. Equipped with a 2 Mbps CAN FD protocol and a CAN FD physical interface, the E522.95 can be connected directly to the Body Control Unit (BCM) via the car in-vehicle network – therefore local lighting control units are no longer needed.
This product was launched in cooperation with Audi AG. Samples of the E522.95 are available.
The demonstrator showed e.g. Coming/Leaving home scenarios, dynamic turn indicator and many other next generation scenarios.
Developed fully according to the ISO 26262 Functional Safety development process, the E522.95 offers a full suite of diagnosis features that ensure reliable system operation of LED drivers and enable achieving ASIL-B ratings at system level. The 16 channel E522.95 LED controller has a maximum output current of 100 mA per channel and supports Elmos’ patented power management methodology ensuring a constant light intensity of the LEDs even under difficult thermal conditions. The E522.95 is offered in a QFN40 package with an exposed die pad.
