●Descriptions
BH1710FVC is an digital Ambient Light Sensor IC for I²C bus interface. This IC is the most suitable to obtain the ambient
light data for adjusting LCD and Keypad backlight power of Mobile phone. It is possible to detect wide range at High
resolution. (1 - 65535 lx).
●Features
1) I²C bus Interface (f / s Mode Support)
2) Spectral responsibility is approximately human eye response
3) Illuminance to Digital Converter
4) Wide range and High resolution. (1 – 65535 lx)
5) Low Current by power down function
6) 50Hz / 60Hz Light noise reject-function
7) 1.8V Logic input interface
8) No need any external parts
9) Light source dependency is little. (ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light)
10) It is possible to select 2 type of I²C slave-address.
11) Adjustable measurement result for influence of optical window
(It is possible to detect min. 0.24 lx, max. 100000 lx by using this function.)
