This device is especially designed for automotive interior applications requesting high dynamic RGB lighting scenarios. This device is an intelligent RGB device, incorporating besides R/G/B LEDs an IC from ams OSRAM. This embedded IC integrates the drivers for the three R/G/B LEDs. The embedded IC includes the optical measurement data of the three R/G/B LEDs as well. An external micro controller can address and control each device in a daisy chain architecture via an open system protocol. The open protocol allows the micro controller to read back these data and to run any color algorithm. It also allows to read back a temperature value to optimize this color algorithm.

The ams OSRAM OSIRE KRTB AELPS1.32 RGB sidelooker device is specifically designed for automotive interior applications. It offers individually addressable LED chips for a maximum of flexibility in terms of color point, driver selection and interconnection. Due to the low profile, the OSIRE KRTB AELPS1.32 is ideally suited for coupling into thin lightguides and enables ultra compact designs.

The OSIRE E3323 is designed for automotive ambient applications. With its compact size, the device offers a maximum of flexibility for various assembly situations. All measurement data of every single LED is made available at 10 and 50 mA via an imprinted data matrix code. This feature helps to reduce the optical measurement effort on customer side.

Silicon Photodiode with Vλ Characteristic

The AS8579 is a capacitive sensor that detects the change of capacity in different applications. The capacitive sensor measures the impedance that originates between a conducting surface (metallic object) and a human being. The IC captures the current of a metal object and applies algorithms to determine the capacitive and resistive information. The outcome information can be read through a SPI Interface that can be also used for IC configuration. This high precision performance sensor also supports a multitude of diagnostic features that meet standard functional safety requirements. The capacitive sensing IC is specifically designed to function in an electro-magnetic environment (EMC) with high magnetic disturbances. This allows the sensor to distinguish in a hands-on application if the driver‘s hand is on the steering wheel or not. The AS8579 is available in an SSOP24 package and operates at a supply voltage of 5V.
