Color Light-To-Digital Converter with Proximity Sensing

The TMD3782x device will perform color temperature

measurement, ambient light sensing (ALS) and proximity

detection with background light rejection. The device detects

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 distance detection, such as in a cell phone

when the user positions the phone close to their ear. IR LED sink

current is factory trimmed to provide consistent proximity

response without requiring customer calibrations. An internal

state machine provides the ability to put the device into a low power

state betweenproximity and RGBC measurements providing very

low average power consumption.

General Description

The color sensing feature is useful in applications such as

backlight control, solid state lighting, reflected LED color

sampler, or fluorescent light color temperature detection. The

integrated IR blocking filter makes this device an excellent

ambient light sensor, color temperature monitor, and general

purpose color sensor.
