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.
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 suitable for lead-free

: IL = 37 µA to 74 µA @EV = 100 lx using fluorescent light
Weight: 0.0054 g (typ.)
: Light current variation width: Ã1.67
(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
