Description

The ALS-PT333-3C/L177 is an ambient light sensor. It consists of a phototransistor in 5mm lamp. EVERLIGHT ALS

series products are good effective solution to the power saving of display backlighting of mobile appliances, such as

the mobile phones, NB and PDAs. Due to the high rejection ratio of infrared radiation, the spectral response of the

ambient light sensor is close to human eyes.

Applications

‧

Ambient light monitoring device for daylight and artificial light

– CCD camera/CCTV security equipment, Street light

‧

Detection of ambient light to control display backlighting

Computing device – TFT LCD monitor for Notebook computer

Consumer device – TFT LCD TV, video camera, digital camera, toys

The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (RL) 2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light, and output saturation voltage: Vout(max.) = Iout(max.) × RL ≦Vout(saturation)＝Vcc－0.4V 6 Copyright Revision :2 © LifecyclePhase: Release Date:2012-11-15 16:50:07.0 2012, Everlight All Rights Reserved.
