TCS3772

Color Light‐to‐Digital Converter with

Proximity Sensing

The TCS3772 device family provides red, green, blue, and clear

(RGBC) light sensing and, when coupled with an external IR LED,

proximity detection. These devices detect light intensity under

a variety of lighting conditions and through a variety of

attenuation materials, including dark glass. The proximity

detection feature allows a large dynamic range of operation for

accurate short distance detection, such as in a cell phone, for

detecting when the user positions the phone close to their ear.

An internal state machine provides the ability to put the device

into a low power state in between proximity and RGBC

measurements providing very low average power

consumption.

The color sensing feature is useful in applications such as LED

RGB backlight control, solid state lighting, reflected LED color

sampler, or fluorescent light color temperature detection. With

the addition of an IR blocking filter, the device is an excellent

ambient light sensor, color temperature monitor, and general

purpose color sensor.
