TMD3700 Color Sensor Module

Digital color sensor, proximity sensor and IR LED in an optical module with 1.8V I2C interface

 

The TMD3700 features advanced proximity measurement, digital ambient light sensing (ALS) and color sensing (RGBC). The 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).

The color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the C, R, G, B channels have a UV and IR blocking filters and a dedicated data converter producing16-bit data simultaneously. This architecture allows applications to accurately measure ambient light and sense color which enables devices to calculate illuminance and color temperature, control display backlight, and chromaticity.

Key Features

  • Small footprint and low profile package (4.00 x 1.75 x 1.00 mm)
  • 45 degree average ALS FOV
  • Wide dynamic range and high sensitivity

Key Benefits

  • Reduced board space requirements and enables low-profile system design
  • Improved ALS angular response for more accurate measurement of lighting environment
  • Operating range of 200 milli-Lux to 60 kilo-Lux enables operation behind dark glass
