TMD26353M

TMD26353M is a miniature proximity sensor module. It 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 TMD2635 applications for wearable products such as true-wireless stereo earbuds, glasses, and watches include power control (automatic power up/down based on user insertion/removal), volume/mode control user detection (up/down/mute based on user touch/tap).
