Ambient LED lighting is becoming increasingly popular in the automotive industry and manufacturers are using it as a differentiator to enhance the driving experience. It also enables OEMs to emphasise their car brand via the colour and styling of the interior lighting, while car dealers can offer consumers the option of customising the lighting settings.
Whereas interior LED modules are currently programmed during the module manufacturing process, with NXP’s new Node Position Detection method, based on an integrated LIN switch, all LED modules can be individually configured even after being mounted in the car offering new levels of flexibility while reducing manufacturing logistics and costs.
The UJA1018 integrates all analogue functions to create a compact ambient lighting solution, including LIN transceiver, LIN switch for Node Position Detection, voltage regulator for microcontroller and drivers for 3-color LED. In addition, the HVSON package will enable small form factor modules. The UJA1018 also meets SAE J2602 and LIN conformance.
“The UJA1018 and its Node Position Detection technology based on Lin switch, enables car OEMs to offer personalised ambient lighting solutions to end consumers. At the same time it saves system costs and simplifies logistics for both OEMs and Tier1 suppliers”, said Toni Versluijs, general manager of In-Vehicle Networking, NXP Semiconductors.
