TMD2635 IR Proximity Detection Module

2-in-1 ultra small proximity detection module 1.8V I²C

特徴

  • Ultra-Small (1.0mm3) 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 and low profile 2.0mm x 1.0mm x 0.5 mm package

利点

  • Ideal for the smallest size applications
  • Enables accurate and stable measurements behind highly diffusive and spectrally distorting materials in low light level environments
  • Compensates for unwanted ambient light photodiode current
  • Enables an additional device to reside on I²C bus with 0x38
  • Enhances industrial design flexibility of sensor apertures sizes and shapes (1.5mm circular or 1x2mm oval)
  • Reduces overall system power consumption
  • Reduce board space requirements and enable low-profile system design

概要

The TMD2635 is an advanced IR proximity sensor module suited for short range proximity measurement detection and offered in the industry's smallest size (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 nearby object detection by photodiode detection of reflected IR energy sourced by the integrated VCSEL emitter. Sensitivity, power consumption, and noise can be optimized with adjustable timing and power. Detect/release events can be interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features advanced crosstalk noise cancellation through a wide range offset adjustments to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction.
