STK32562 Ambient Light Sensor and Proximity Sensor with I2C interface Datasheet Version - 0.9.0 Hazardous Substance Free RoHS / REACH pliant STK32562 REV 0.9.0 1. OVERVIEW Description The STK32562 is an integrated ambient and infrared light to digital converter with I2C interface. This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function. For ambient light sensing, the STK32562 incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be close-to human eye. The STK32562 is suitable for detecting a wide range of light intensity environment. For proximity sensing, the STK32562 also incorporates a photodiode, timing controller and ADC in the same chip. The spectral response of STK32562 is optimized for wavelength 940nm infrared light. The STK32562 provides programmable current setting to drive IR LED and employs a noise cancellation scheme to highly reject unwanted ambient IR noise. The STK32562 has excellent temperature pensation, robust on-chip refresh rate setting without external ponents. Software shutdown mode control is provided for power saving application. The STK32562 operating voltage range is 1.7V to 2.0V.
