BH1772GLC 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. 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 key.
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) Built in ambient light cancelation (Proximity sensor function) 9) Built in configurable IrLED current driver
●Applications Mobile phone, DSC, Portable.
