TMD3719

ALS/Color and Proximity Sensor

The TMD3719 features ambient light and color (RGB) sensing,

flicker detection and proximity detection. The device integrates

three IR VCSELs and an advanced VCSEL driver within a

low-profile 6.35mm x 3.00mm x 1.00mm package.

The ambient light and color sensing function provides six

concurrent ambient light sensing channels: Red, Green, Blue,

Clear, Leakage and Wideband. The RGBL and Clear channels

have a UV/IR blocking filter. This architecture accurately

measures ambient light and enables the calculation of

illuminance, chromaticity, and color temperature to manage

display appearance.

The device integrates direct detection of ambient light flicker

for 4 selectable frequency bins. Flicker detection is executed in

parallel with ambient light and color sensing. The flicker

detection engine can also buffer data for calculating other

flicker frequencies externally.

The proximity function synchronizes IR emission and detection

to sense nearby objects. The architecture of the engine features

self-maximizing dynamic range, ambient light subtraction,

advanced crosstalk cancelation, and interrupt-driven I²C

communication. Sensitivity, power consumption, and noise can

be optimized with adjustable IR VCSEL timing and power. The

proximity engine recognizes detect/release events and

produces a configurable interrupt whenever the proximity

result crosses upper or lower threshold settings.
