TMD3702VC

Narrow ALS, Color and Proximity

Sensor Module

The TMD3702VC features proximity detection, color sense

(RGBC+IR), and digital ambient light sensing (ALS). The

extremely narrow 1.44mm module incorporates an IR VCSEL

and factory calibrated VCSEL driver. The proximity detection

feature provides object detection (e.g. mobile device screen to

user’s ear) by photodiode detection of reflected IR energy

(sourced by the integrated VCSEL). Detect/release events are

interrupt driven, and occur when proximity result crosses upper

and/or lower threshold settings. The proximity engine features

a wide range offset adjustment to compensate for unwanted IR

energy reflection at the sensor. Proximity results are further

improved by automatic ambient light subtraction. The color

photodiodes have UV and IR blocking filters and dedicated data

converters producing 16-bit data. This architecture allows

applications to accurately measure ambient light which

enables devices to calculate illuminance and color temperature

to control display backlight and chromaticity.
