Other Equipment Requiring Luminosity Adjustment
The TPS852 is an ultra-compact surface-mount photo-IC for
illuminance sensors which incorporates a photodiode and current amp
circuit in a single chip.
The sensitivity is superior to that of a phototransistor, and exhibits
little variation.
It has spectral sensitivity closer to luminous efficiency and excellent
output linearity.
With its ultra-compact surface-mount package, this photo-IC can be
used as the power-saving control for domestic appliances or for
backlighting for displays in cellular phones, this device enables low
power consumption to be achieved.
Ultra-compact and light surface-mount package: 1.6 × 1.6 × 0.55 mm
Excellent output linearity of illuminance
Little fluctuation in light current and high level of sensitivity
: IL = 40 μA (typ.) @EV = 100 lx using fluorescent light
: Light current variation width: ×1.67
(when light current classification is
specified.)
: Little temperature fluctuation
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.)

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
When Vcc is turned on it takes at least 200 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) To avoid moisture absorption by the resin, the product is packed in an aluminum envelope with silica
gel.
(2) 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: 5°C to 30°C, Relative humidity: 60% (max), Time: 168 h (max)
(3) Baking in taping with reel 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: 60°C for 12 h or longer, Perform baking only once
Mounting Precautions
(1) Do not apply stress to the resin at high temperature.
(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.
Mounting Methods
(1) Reflow soldering
Package surface temperature: 260°C (max)
Please perform reflow soldering using the following reference temperature profile.
Perform reflow soldering no more than twice.
Please perform the first reflow soldering within 168 h after opening the package with reference to
the above temperature profile.
Second reflow soldering
In case of second reflow soldering, it should be performed within 168 h after first reflow under the
above conditions.
Storage conditions before second reflow soldering: 30°C, 70% RH or lower
Do not perform flow soldering.
Make any necessary soldering correction manually.
(do not do this more than once for any given pin.)
