TPS855(F) TOSHIBA Photo-IC Silicon Epitaxial Planar TPS855(F) Lead(Pb)-Free Luminosity Adjustment for TV Screens, CRT Monitors and Liquid-crystal Display Monitors Other Equipment Requiring Luminosity Adjustment The TPS855(F) is a linear-output photo-IC which incorporates a photodiode and a current amp circuit in a single chip. This photo-IC is current output type, so can set up output voltage freely by arbitrary load resistance. • High sensitivity :IL = 280 μA (typ.) @EV = 100 lx Using the fluorescent light • Little fluctuation in light current • Excellent illumination output linearity • Open-emitter output • Side-view package • Environmentally friendly silicon used as chip material instead of CdS Suitable as a substitute for CdS-based products : 1.67 times width ( ±25% typ.) Absolute Maximum Ratings (Ta = 25°C) Characteristics Supply voltage Output voltage Light current Symbol Rating Unit VCC −0.5 to 7 V VOUT < = VCC V IL 10 mA Permissible power dissipation P 150 mW Operating temperature range Topr −25 to 85 °C Storage temperature range Tstg −40 to 100 °C Soldering temperature range (5s) ( Note 1 ) Tsol 260 °C 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).

During this period the output signal is unstable and may change. Please take this into account. Mounting Precautions (1) (2) (3) When forming the leads, bend each lead under the lead stopper. Soldering must be performed after the leads have been formed. Soldering must be performed under the stopper. To stabileze the power line, insert a bypass capacitor of up to 0.01μF between VCC and GND, close to the device. 4 2007-10-01 TPS855(F) P – Ta ILEAK – Ta (μA) VCC = 5 V Please refer to Figure 2. 100 Dark current 0.1 50 20 40 60 Ambient temperature 80 Ta 0.001 20 100 (typ.) 1.4 1000 1.2 100 Ta = 25°C VCC = 5 V 図 1 参照 A 光源 蛍光灯 10 10 100 Illuminance Relative 1000 EV (V) VO Output voltage 0.4 Ta = 25°C Please refer to Figure 1.
