仕様・特性

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: 2.0mm × 2.1mm × 0.7 mm • Excellent output linearity of illuminance • Little fluctuation in light current and high level of sensitivity: • • Light current variation width = ×1.67 (when light current classification is specified.) • • TOSHIBA IL = 37 μA to 74 μA @EV = 100 lx using fluorescent light 0-2D1 Little temperature fluctuation 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 Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Supply voltage VCC −0.5 to 7 V Output voltage VOUT ≤ VCC V Light current IL 5 mA Permissible power dissipation P 35 mW Operating temperature range Topr −30 to 85 °C Storage temperature range Tstg −40 to 100 °C Tsol 260 °C Soldering temperature range (Note 1) Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 1: The reflow time and the recommended temperature profile are shown in the section entitled Handling Precautions. 1 2008-07-10
