The TPS853 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 soldering and reflow soldering: 2.0 × 2.1 × 0.7 mm
· Excellent output linearity of illuminance
· Little fluctuation in light current and high level of sensitivity
: IL = 37 μA to 74 μA @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 = 2.2 V to 5.5 V
