Product Summary

The BH1772GLC-E2 is an Ambient Light Sensor IC into which optical proximity sensor and digital ambient light senor are unified. Proximity sensor part detects the human or object approach by reflection of infrared LED(IrLED) light. Ambient light sensor part can detect the wide range illuminance from the dark up to under direct sun light. The illuminant intensity of LCD display and keypad can be adjusted, so lower current consumption or higher visibility are possible. The applications of the BH1772GLC-E2 include Mobile phone, DSC, Portable game, Camcoder, Car navigation, PDA, LCD display etc.
