| TPS820 Preliminary TOSHIBA Photo IC Silicon Epitaxial Planar TPS820 Photo-Electric Switches Copiers, Printers, and Facsimiles Luminosity Adjustment for Various Types of Equipment The TPS820 is a linear output photo-IC (current output type) which incorporates a photodiode and a current amp circuit in a single chip. The sensitivity is superior to that of a phototransistor and its illuminance output linearity is excellent. * * * * * * * High sensitivity: IL = 2.5 mA (typ.) @E = 0.1 mW/cm2 Little fluctuation in light current Output linearity of illuminance is excellent. Low current consumption: ICC = 1 A (max) at VCC = 5 V Housed in compact side-view epoxy resin package Black package impermeable to visible light The TPS820 is suitable for use in combination with the TLN117 infrared LED lamp whose package size is the same.

Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when utilizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the most recent products specifications. Also, please keep in mind the precautions and conditions set forth in the TOSHIBA Semiconductor Reliability Handbook. * The information contained herein is presented only as a guide for the applications of our products.

To stabilize the power line, insert a bypass capacitor of up to 0.01 F between VCC and GND, close to the device. When the power is turned on, the output value will fluctuate for 1 ms as the internal circuit stabilizes. 2000-06-06 2/4 TPS820 P - Ta 300 10 Id - Ta (typ.)
