TPS818
TOSHIBA Photo IC Silicon Epitaxial Planar
TPS818
Luminosity Adjustment for TV Screens, CRT Monitors and Liquid-crystal Display Monitors Notebook PCs and Portable Information Devices Cellular and PHS Phones Other Equipment Requiring Luminosity Adjustment
The TPS818 is a linear-output (current output type) photo-IC which incorporates a photodiode and a current amp circuit in a single chip. A luminous efficiency correction filter mounted on the detector ensures accurate luminosity output levels. The device's excellent output linearity enables automatic adjustment of the luminosity of a TV screen or PC monitor in accordance with the ambient brightness of the operating environment. * * * * * * * * High sensitivity : Light current IL = 240 A (typ.) @EV = 100 lx Little fluctuation in light current : 1.67 times width (25 typ.) Low current consumption : ICC = 1 A (max) @VCC = 5.5 V Excellent illumination output linearity Luminous efficiency correction filter mounted on detector: p = 560 mm (typ.) Open-emitter output Side-view package Environmentally friendly silicon used as chip material instead of CdS Suitable as a substitute for CdS-based products TOSHIBA Weight: 0.22 g (typ.) Unit: mm

Handling Precautions
* * * 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 stabilize the power line, insert a bypass capacitor of up to 0.01 mF between VCC and GND, close to the device.
