OSRAM OSIRE™ E3731i, KRTBI D2LM31.31

×

Description

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 the Open System Protocol (OSP). OSP 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. OSIRE™ E3731i is compliant with all known patents and rights in countries with an automotive production footprint. In particular, neither rights in terms of temperature compensation within the LED nor SPI communication with controllers inside an LED are affected.
