Description

The ALS-PT17-51C/L177/TR8 is a low cost ambient light sensor, consisting of phototransistor

in miniature SMD. EVERLIGHT ALS series product are a 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 that of human eyes.

Applications

‧Detection of ambient light to control display backlighting

Mobile devices – mobile phones, PDAs

Computing device – TFT LCD monitor for Notebook computer

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

‧Automatic residential and commercial management

‧Automatic contrast enhancement for electronic signboard

‧Ambient light monitoring device for daylight and artificial light

– Street light, CCD/CCTV

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 Everlight Electronics Co., Ltd.

ALS-PT17-51C/L177/TR8 Surface - Mount Ambient Light Sensor Recommended method of storage Reflow Terms: JEDEC Level 4 Specification Dry box storage is recommended as soon as the aluminum bag has been opened prevent 1. Over-current-proof Customer must apply resistors for protection, otherwise slight voltage shift might cause big current happen. (Burned-out might happen). 2. Storage (1) Do not open moisture proof bag before components are ready to use.
