Description
The ALS-PDIC15-21B/TR8 is a compact surface mount photo-sensor IC for detecting ambient
light illuminating intensity. The sensitivity is superior to that of a phototransistor, and exhibits
little chip-to-chip variation. It has excellent spectral sensitivity to the illuminating light source
and excellent output linearity. Due to very low photo current fluctuation versus temperature
change, ALS-PDIC15-21B/TR8 is very suitable for hand-held or outdoor application device.
Applications
‧Detection of ambient light to control display backlighting
Mobile devices – Mobile phones, PDAs, GPS
Computing device – TFT LCD monitor for Notebook computer
Consumer device – TFT LCD TV, Plasma TV
‧Automatic residential and commercial management
‧Automatic contrast enhancement for electronic signboard
‧Ambient light monitoring device for daylight and artificial light
– Street light
