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 TOSHIBA ― circuit in a single chip. Weight: 0.0054 g (typ.) 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: 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 • • • 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.)

Please take this into account. Moisture-Proof Packing (1) (2) To avoid moisture absorption by the resin, the product is packed in an aluminum envelope with silica gel. Since the optical characteristics of the device can be affected during soldering by vaporization resulting from prior absorption of moisture and they should therefore be stored under the following conditions: Temperature: 5°C to 30°C, Relative humidity: 60% (max), Time: 168 h (max) Baking is required if the devices have been store unopened for more than six months or if the aluminum envelope has been opened for more than 168 h. These devices are packed on tapes; hence, please avoid baking at high temperature. Recommended baking conditions: 60°C for 12 h or longer (3) Mounting Precautions (1) (2) (3) Do not apply stress to the resin at high temperature. The resin part is easily scratched, so avoid friction with hard materials. When installing the assembly board in equipment, ensure that this product does not come into contact with other components. Mounting Methods (1) Reflow soldering • Package surface temperature: 260°C (max) • Please perform reflow soldering using the following reference temperature profile. Perform reflow soldering no more than twice. Temperature (°C) → 260°C max 230°C 190°C 180°C Preheating part 60 s to 120 s 30 s to 50 s Heating part Time (s) → • • Please perform the first reflow soldering within 168 h after opening the package with reference to the above temperature profile. Second reflow soldering In case of second reflow soldering, it should be performed within 168 h after first reflow under the above conditions. Storage conditions before second reflow soldering: 30°C, 60% RH or lower • • Do not perform flow soldering. Make any necessary soldering correction manually.
