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 A (typ.) @EV = 100 lx Using the fluorescent light Little fluctuation in light current : 1.67 times width ( 25% typ.) 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

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: Solder under the lead stopper.

Handling Precautions
At power-on in darkness, the internal circuit takes about 50 ms to stabilize. 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 0.01F between VCC and GND, close to the device.
