No.10046EBT07
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.)
Applications
Mobile phone, LCD TV, NOTE PC, Portable game machine, Digital camera, Digital video camera, Car navigation, PDA,
LCD display

Application circuit example of DVI terminal
The DVI terminal is an asynchronous reset terminal. Please note that there is a possibility that IC doesn't operate normally if
the reset section is not installed after the start-up of VCC.
(Please refer to the paragraph of "Timing chart for VCC and DVI power supply sequence")
The description concerning SDA and the terminal SCL is omitted in this application circuit example. Please design the
application the standard of the I2C bus as it finishes being satisfactory. Moreover, the description concerning the terminal
ADDR is omitted. Please refer to the paragraph of "Timing chart for VCC and DVI power supply sequence" about the
terminal ADDR design.
