Document Summary

The SIP3635LR0G is a three-in-one light sensor module that integrates a high-performance R/G/B/IR color sensor, an infrared proximity sensor, and an infrared LED with a peak wavelength of 940nm. The color sensor measures ambient light illuminance, color temperature, and chromaticity, while the proximity sensor is sensitive to the signal of infrared LED light reflected from objects. The response value is output through the I2C communication port.

The SIP3635LR0G color sensor features four ALS channels. Four sets of photodiodes with ultra-high sensitivity and low dark current, each equipped with specific optical filters, are key components of the device. These photodiodes appropriately mimic the human eye's response and accurately respond to various light sources. Precise timing control and independent gain settings for different channels facilitate the measurement of a wide range of illuminance and color temperature.

The proximity sensor in the SIP3635LR0G features two proximity photodiodes covered with appropriate optical filters to match the 940nm infrared LED emitter and filter out ambient light noise. The built-in signal chain further performs ambient light cancellation and noise suppression, resulting in a higher signal-to-noise ratio response for reflected light from objects. The SIP3635LR0G incorporates a configurable infrared LED driver to drive the module's built-in 940nm infrared LED emitter. This driver supports factory calibration for a more consistent proximity response, contributing to a better user experience in object detection applications.

The SIP3635LR0G features a temperature drift compensation design, which helps to achieve a more stable response.
