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 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 x 2.1 x 0.7 mm TOSHIBA ?

NC 3 2005-07-21 TPS853 Moisture-Proof Packing (1) (2) (3) 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: 5C to 30C, Relative humidity: 70% (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: 60C for 12 h or longer 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 Reflow soldering * Package surface temperature: 260C (max) * Please perform reflow soldering using the following reference temperature profile. Perform reflow soldering no more than twice.
