TPS852

TPS852 TOSHIBA Photo-IC Silicon Epitaxial Planar TPS852 Mobile Phones Notebook PCs, PDAs Video cameras, Digital Still Cameras Other Equipment Requiring Luminosity Adjustment The TPS852 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: 1.6 × 1.6 × 0.55 mm Excellent output linearity of illuminance Little fluctuation in light current and high level of sensitivity TOSHIBA ― : IL = 40 μA (typ.) @EV = 100 lx using fluorescent light Weight: 0.003 g (typ.) : Light current variation width: ×1.67 (when light current classification is specified.) : Little temperature fluctuation 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 Lead(Pb)-Free Absolute Maximum Ratings (Ta = 25°C) Characteristics Supply volta...
