BH1772GLC - 1 Chip Optical Proximity Sensor + Ambient Light Sensor

Description

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.

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) Built in ambient light cancelation (Proximity sens.

Ambient Light Sensor ICs 1 Chip Optical Proximity Sensor + Ambient Light Sensor IC BH1772GLC No.11046EBT12 ●Descriptions 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 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.
