General Description
RPR-0521RS is a module which integrates optical proximity, digital ambient light sensor IC, and infrared LED (IrLED). Proximity sensor (PS) part detects the human or object approaching by the reflection of IrLED light. Ambient light sensor (ALS) part detects the wide range of illumination; from the dark environment to the direct sun light. The illuminant intensity of LCD display and keypad can be adjusted by using RPR-0521RS. It enables lowering current consumption and/or improving the visibility under the bright environment.

FEATUREs
1) Compatible to I2C bus interface ( f/s mode support )
2) Compatible to 1.8V logic interface
3) Low Current consumption by power down function/mode
4) There are two ALS outputs; peaks of spectrum responses are in visible light (Data0) and in infrared light (Data1) for calculating illuminance.
5) Correspond to very wide range of light intensity
6) Rejecting 50Hz/60Hz light noise (ALS function)
7) Detection range of proximity sensor is around 1 - 100mm (adjustable by I2C)
8) Built-in current configurable IrLED driver

APPLICATION
   Smart phone, Mobile phone, Digital Still Camera, Portable game, Camcoder, PDA, LCD display etc.
