TMD2712

ALS + Proximity Sensor Module

The TMD2712 features proximity detection and digital ambient

light sensing (ALS). The extremely tiny 1mm x 2mm 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 ALS and IR photodiodes have dedicated

data converters producing 16-bit data. This architecture allows

applications to accurately measure ambient light which

enables devices to calculate illuminance to control display

backlight.
