Description

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 m 
• Excellent output linearity of illuminance  
• Little fluctuation in light current and high level of sensitivity
   : IL = 40 A (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.)  
    
•  Low supply voltage, making device suitable for battery-powered equipment: VCC = 2.7 V to 5.5 V 
• Lead(Pb)-Free

Application:

• Mobile Phones
• Notebook PCs, PDAs
• Video cameras, Digital Still Cameras
• Other Equipment Requiring Luminosity Adjustment
