ams OSRAM OSIRE® E3731i

OSIRE^® E3731i 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 LED drivers and also includes the optical measurement data of the three R/G/B LED chips.

An external micro controller can address and control each device in a daisy chain architecture via an Open System Protocol (OSP).
