TPS851

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 JEDEC JEITA TOSHIBA ― ― ― Weight: 0.0054 g (typ.) · · Built-in luminous-efficiency correction function, reduced sensitivity variations due to various light sources : IL (using incandescent light)/IL (using fluorescent light) = 1.2 (typ.) Low supply voltage, making device suitable for battery-powered equipment: VCC = 2.7 V to 5.5 V...
