TPS853

TPS853 TOSHIBA Photo-IC Silicon Epitaxial Planar TPS853 Mobile Phones, PHS Notebook PCs, PDAs Video cameras, Digital Still Cameras Other Equipment Requiring Luminosity Adjustment The TPS853 is an ultra-compact surface-mount photo-IC for illuminance sensors which incorporates a photodiode and current amp TOSHIBA ― circuit in a single chip. The sensitivity is superior to that of a phototransistor, and exhibits Weight: 0.0054 g (typ.) little variation. It has spectral sensitivity closer to luminous efficiency and excellent output linearity. This photo-IC can be used as the power-saving control for domestic appliances or for backlighting for displays in cellular phones. This device includes stand-by function which can reduce the power consumption of the system. Ultra-compact and light surface-mount package: 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 in light current 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 = 2.2 V to 5.5 V Lead(Pb)-Free Absolute Maximum Ratings (Ta = 25°C) Characteristics...
