LIN controlled interior LED lighting IC for cars

NXP Semiconductors N.V. has introduces the UJA1018 for LED ambient lighting (interior lighting) applications in vehicles. NXP says the UJA1018 is designed for LIN networks (Local Interconnect Networks) and is the first ASSP (Application Specific Standard Product) for ambient lighting with Node Position Detection. This enables LIN addresses of LED modules to be individually programmed after being installed in the car, rather than during module manufacturing. Ambient LED lighting is increasingly popular in the automotive industry. Car manufacturers are using it as a differentiator to enhance the driving experience. It also enables OEMs to emphasize their car brand via the color and styling of the interior lighting, while car dealers can offer consumers the option of customizing the lighting settings, explains NXP.

The specialty of this device is based on an integrated LIN switch, all LED modules can be individually configured even after being mounted in the car.

The UJA1018 integrates LIN transceiver, LIN switch for Node Position Detection, voltage regulator for microcontroller and drivers for 3-color LED.

“With the UJA1018 and its unique Node Position Detection technology based on LIN switch, NXP enables car OEMs to offer personalized ambient lighting solutions to end consumers. At the same time it saves system costs and simplifies logistics for both OEMs and Tier1 suppliers,” says Toni Versluijs, general manager of In-Vehicle Networking, NXP Semiconductors. “This underpins our leadership position as the de-facto In-Vehicle Network solution provider and our commitment to connect the car in present and in future”.

Dr. Herbert Wambsganß, head of development at HELLA Interior Lighting Systems commented: “The UJA1018 enables HELLA to introduce a very compact LED ambient lighting solution that fits every interior location. The Node Position Detection by means of the integrated LIN switch allows configuration of each ambient lighting module once mounted in the car. Thus, all modules in the car can be kept the same which allows a high level of reuse and greatly simplifies the logistics.”
