[v1-03] 2018-Dec-19 Document Feedback TCS3701 ALS/Color and Proximity Sensor for Use Behind OLED Displays The TCS3701 features ambient light and color (RGB) sensing in parallel with proximity detect ion. The device comes in a low-profile and small footpr int, L2.5mm x W2.0mm x H0.5mm package. The Ambient Light and Color Sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The RGB an d 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 internal IR LED driver needs to be connected to an external emitter. The architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced crosstalk cancelation, 14-bit data output and interrupt-driven I²C communication. 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. General Description
