BH1730FVC-TR

General Description

BH1730FVC is a digital Ambient Light Sensor IC with I 2 C

bus interface. This IC is most suitable for obtaining

ambient light data for adjusting LCD and backlight power

of TV and mobile phone. It is capable of detecting a very

wide range of illuminance.

Features

■  I 2 C bus Interface

f/s Mode Support, Slave Address "0101001"

■  2 outputs with peak wavelengths of visible light and

infrared light respectively.

■  Illuminance to digital converter

■  Low current by power down function

■  50Hz / 60Hz light noise reject function

■  Light source dependency is small by the calculation

using 2 outputs. (e.g. Incandescent lamp, Fluorescent

lamp, Halogen lamp, White LED and Sun light)
