Overview :
The oT852 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. It is suitable in the power-saving control for backlighting displays in Smart phone, Notebook PC, Tablet PC, GPS, PDAs, Digital cameras, Video cameras, LCD monitor, TV, Energy saving lamp.
