Description
The ALS-PDIC17-77B/TR8 is consisting of a photodiode and a current amplification IC.
EVERLIGHT ALS series product is 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

Recommended method of storage
ALS-PDIC17-77B/TR8
1. Do not open moisture proof bag before devices are ready to use.
2. Shelf life in sealed bag from the bag seal date:
18 months at 10°C~30°C and < 90% RH.
3. After opening the package, the devices must be stored at 10°C~30°C and 60%RH,
and used within 1 year (floor life).
4. If the moisture absorbent material (desiccant material) has faded or unopened bag has
exceeded the shelf life or devices (out of bag) have exceeded the floor life, baking
treatment is required.
5. If baking is required, refer to IPC/JEDEC J-STD-033 for bake procedure or recommend
the following conditions:
192 hours at 40°C +5/–0°C and < 5 % RH (reeled/tubed/loose units) or
96 hours at 60°C ± 5°C and < 5 % RH (reeled/tubed/loose units) or
24 hours at 125°C ± 5°C, not suitable for reel or tubes.
Recommended Solder Profile
Notice:
(1) Reflow soldering should not be done more than two times.
(2) When soldering, do not put stress on the devices during heating.
(3) After soldering, do not warp the circuit board.
