Ambient Light Sensor IC

BH1771GLC

No.11046EBT11

●Descriptions

BH1771GLC is the 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. And this device can drive maximum 3 IrLEDs,

and touch-less motion detection function can be implemented. Ambient light 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.

●Features

1) Correspond to I²C bus interface ( f/s mode & Hs mode support )

2) Low Current by power down function

3) Correspond to 1.8V logic interface

4) ALS spectral responsibility is approximately human eye response ( Peak wavelength : typ. 550nm )

5) Correspond to wide range of light intensity ( 1-65535 lx range )

6) Rejecting 50Hz/60Hz light noise (ALS function)

7) Detection range of proximity sensor is around 10 - 100mm (configurable by I²C bus)

8) Touch-less motion detection function

9) Built in ambient light cancelation (Proximity sensor function)

10) Built in configurable IrLED current driver

●Applications

Mobile phone, DSC, Portable game, Camcoder, Car navigation, PDA, LCD display etc.
