No Preview Available ! Ambient Light Sensor ICs Analog Current Output Type Ambient Light Sensor IC BH1680FVC No.12046EBT14 ●Descriptions BH1680FVC is an analog current output ambient light sensor. This IC can detect the illuminance from 0lx to 50000lx. It is the most suitable to obtain the ambient light data for adjusting LCD and Keypad backlight of Mobile phone for power saving and better visibility. It is suitable also for the use of optical window that the visible light transmission is low because of the high sensitivity type. ●Features 1) Compact surface mount package 1.6 x 1.6 mm 2) Output current in proportion to brightness 3) Suitable for optical window that the visible light transmission is low (High sensitivity type) 4) The influence of infrared is very small by an infrared cut filter 5) Supply voltage operates from 2.4V to 5.5V 6) Built-in shutdown function 7) 3 steps controllable output current gain 8) 1.8V logic input interface 9) Low sensitivity variation (+/-15%) ●Applications Mobile phone, LCD TV, PDP TV, Laptop PC, Portable game console, Digital camera, Digital video camera, LCD display ●Absolute Maximum Ratings Parameter Symbol Limits Units Supply Voltage Vmax www.DataSheet.co.kr 7 V Operating Temperature Topr -40~85 ℃ Storage Temperature Tstg -40~100 ℃ Iout Current Ioutmax 7.5 mA Power Dissipation Pd 165※ mW ※ 70mm × 70mm × 1.6mm glass epoxy board.
