TMD3725

ALS, Color and Proximity Sensor

Module

The device features advanced proximity measurement, color

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

package has been designed to accommodate a “single hole”

aperture approach. The slim module incorporates an IR LED and

factory calibrated LED 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 LED). Detect/release events are interrupt

driven, and occur when proximity result crosses upper and/or

lower threshold settings. The proximity engine features offset

adjustment registers to compensate for unwanted IR energy

reflection at the sensor. Proximity results are further improved

by automatic ambient light subtraction. The ALS detection

feature provides photopic light intensity data. The color

photodiodes have UV and IR blocking filters and a 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.
