TMD2725
ALS, and Small Aperture Proximity
Sensor Module
General Description
The device features advanced proximity measurement and
digital ambient light sensing (ALS). The package has been
designed to accommodate a single small 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 ALS
photodiode has UV and IR blocking filters and a dedicated data
converter producing 16-bit data. This architecture allows
applications to accurately measure ambient light which
enables devices to calculate illuminance to control display
backlight.
