TMD2635
Miniature Proximity Sensor Module
General Description The TMD2635 features advanced proximity measurement in a
tiny (1.0mm x 2.0mm) and thin (0.5mm) optical land grid array
module that incorporates a 940nm IR VCSEL and is factory
calibrated for IR proximity response. The proximity detection
feature provides object detection (e.g. close proximity) by
photodiode detection of reflected IR energy sourced by the
integrated VCSEL emitter. Detect/release events can be
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.
