TSL2585

Miniature Ambient Light Sensor with

UV and Light Flicker Detection

The TSL2585 incorporates Photopic, IR and UV photodiodes

that are connected to 3 modulators, provides concurrent

ambient light sensing, UV sensing and light flicker detection.

The device comes in a low-profile and small footprint,

L2.0mm x W1.0mm x H0.35mm OLGA package.

The Photopic photodiode area is covered with an optimized

Photopic filter. In association with dedicated IR channel, this

architecture accurately measures ambient light and enables the

calculation of irradiance of different light sources. Calculation

results help to automatically optimize display brightness under

different lighting conditions for a better user experience.

The device also integrates functionality of ambient light flicker

detection. It is executed in parallel with ambient light sensing

by using the same photodiodes. The flicker detection engine

will sample and buffer data for calculating flicker frequencies

externally on a host CPU.

The UV photodiode area is covered with a band-pass UV filter.

In combination with Photopic and IR channels, it is possible to

estimate ambient UV index by running an algorithm externally

on a host CPU.
