TPS853
Mobile Phones, PHS Notebook PCs, PDAs Video cameras, Digital Still Cameras Other Equipment Requiring Luminosity Adjustment
The TPS853 is an ultra-compact surface-mount photo-IC for illuminance sensors which incorporates a photodiode and current amp TOSHIBA circuit in a single chip. The sensitivity is superior to that of a phototransistor, and exhibits Weight: 0.0054 g (typ.) little variation. It has spectral sensitivity closer to luminous efficiency and excellent output linearity. This photo-IC can be used as the power-saving control for domestic appliances or for backlighting for displays in cellular phones. This device includes stand-by function which can reduce the power consumption of the system. * * * Ultra-compact and light surface-mount package: 2.0 x 2.1 x 0.7 mm Excellent output linearity of illuminance Little fluctuation in light current and high level of sensitivity : IL = 37 A to 74 A @EV = 100 lx using fluorescent light : Light current variation width: x1.67 (when light current classification is specified.) : Little temperature fluctuation in light current 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 = 2.2 V to 5.5 V Lead(Pb)-Free

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.

Handling Precautions
Insert a bypass condenser of up to 0.1F between Vcc and GND near the device to stabilize the power supply line. When Vcc is turned on it takes at least 100 ms for the internal circuit to stabilize. During this time the output signal is unstable. Please do not use the unstable signal as the output signal.
Moisture-Proof Packing
(1) (2) To avoid moisture absorption by the resin, the product is packed in an aluminum envelope with silica gel. Since the optical characteristics of the device can be affected during soldering by vaporization resulting from prior absorption of moisture and they should therefore be stored under the following conditions: Temperature: 5C to 30C, Relative humidity: 70% (max), Time: 168 h (max) Baking is required if the devices have been store unopened for more than six months or if the aluminum envelope has been opened for more than 168 h. These devices are packed on tapes; hence, please avoid baking at high temperature. Recommended baking conditions: 60C for 12 h or longer

Mounting Precautions
TPS853 uses a clear resin, and delicate handling is necessary for it. The characteristic change or the product might be damaged by the handling method of mounting. Please note the following and handle the product. (1) Do not apply stress to the resin at high temperature. Time until the product returns at the normal temperature after mounting of the reflow is different according to the mounting substrate and the environment. Please do not give the stress with heat remained in the product. (2) The resin part is easily scratched, so avoid friction with hard materials. (3) When installing the assembly board in equipment, ensure that this product does not come into contact with other components. (4) Please confirm the heat contraction of the substrate of the reflow mounting doesn't influence the product. The load is given to the product by mounting that the heat contraction is large on the substrate and the installation position of the substrate. Please note that the characteristic changes or the product might be damaged.
