ams OSRAM TMD2636 IR Proximity Detection Module

ams OSRAM TMD2636 IR Proximity Detection Module features advanced proximity measurement and incorporates a 940nm IR VCSEL. The module is housed in a tiny (1.0mm x 2.0mm) and extremely thin (0.35mm) optical land grid array. It’s 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.

Features

  • Low-profile (0.35mm) and ultra-small (0.7mm³) volumetric size
  • Proximity crosstalk compensation
  • 940nm IR proximity with automatic ambient light subtraction
  • Automatic single alternative I²C address option
  • Split near/far photodiodes and offset emitter/detector placement
  • 0.18µm process technology with 1.8V I²C
  • Small footprint 2.0mm x 1.0mm x 0.35mm package

Applications

  • Wearable products
  • True-wireless stereo earbuds, glasses, and watches
  • Power control (automatic power up/down based on user insertion/removal)
  • Volume/mode control user detection (up/down/mute based on user touch/tap)
