TPS851
The TPS851 is an ultra-compact surface-mount photo-IC for
illuminance sensors which incorporates a photodiode and current amp
circuit in a single chip.

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: 2.0 × 2.1 × 0.7 mm
• Excellent output linearity of illuminance
• Little fluctuation in light current and high level of sensitivity
: I_L = 37 μA to 74 μA @E_V = 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
: I_L (using incandescent light)/I_L (using fluorescent light) = 1.2 (typ.)
• Low supply voltage, making device suitable for battery-powered equipment: V_CC = 2.7 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.
