TPS851
TOSHIBA Photo IC Silicon Epitaxial Planar
TPS851
Mobile Phones, PHS Notebook PCs, PDAs Video cameras, Digital Still Cameras Other Equipment Requiring Luminosity Adjustment
The TPS851 is an ultra-compact surface-mount photo-IC for illuminance sensors which incorporates a photodiode and current amp circuit in a single chip. The sensitivity is superior to that of a phototransistor, and exhibits little variation. It has spectral sensitivity closer to luminous efficiency and excellent output linearity. With its ultra-compact surface-mount package, this photo-IC can be used as the power-saving control for domestic appliances or for backlighting for displays in cellular phones, this device enables low power consumption to be achieved.
· · ·
Ultra-compact and light surface-mount package suitable for lead-free soldering and reflow soldering: 2.0 × 2.1 × 0.7 mm Excellent output linearity of illuminance Little fluctuation in light current and high level of sensitivity : IL = 37 µA to 74 µA @EV = 100 lx using fluorescent light : Light current variation width: ×1.67 (when light current classification is specified.) : Little temperature fluctuation
