General Description

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 producing 16-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.

This product suits for the following applications:

  • Color sensing for display color management or camera image enhancement
  • Ambient light sensing
  • Proximity detection for mobile phone touchscreen disable
