Remark

General Description

The TCS3701 is a very-high sensitivity light-to-digital converter that features ambient light and color (RGB) sensing in parallel with IR proximity detection. The Ambient light and color sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The RGB and Clear channels have a UV/IR blocking filter. This architecture accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance. The proximity function synchronizes IR emission and detection to sense nearby objects. The IR driver needs to be connected to an external LED or VCSEL emitter. The architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced optical crosstalk noise cancellation, 14-bit data output and interrupt-driven 1.8V I²C communications interface. Sensitivity, power consumption, and noise can be optimized with adjustable IR LED timing and power. The proximity engine recognizes detect/release events and produces a configurable interrupt whenever the proximity result crosses upper or lower threshold settings.

This product suits for the following applications:

  • Display backlight control
  • Display management
  • Ambient light sensing
  • Color temperature sensing to assist backlight, camera, and flash control
