The TPS856 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.

This device includes stand-by function which can reduce the power consumption.

? Ultra-compact and light surface-mount package: 1.6 × 1.6 × 0.55 mm

? Excellent output linearity of illuminance

? Little fluctuation in light current and high level of sensitivity

: IL = 57 μA (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) = 1.0 (typ.)

? Low supply voltage, making device suitable for battery-powered equipment: VCC = 1.8 V to 5.5 V

? Lead(Pb)-Free
