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 !á 1.6 !á 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: !á1.67
(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
