Product Summary

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.

Parametrics

tps852 absolute maximum ratings: (1)Supply voltage VCC -0.5 to 7 V; (2)Output voltage VOUT <= VCC V; (3)Light current IL 5 mA; (4)Permissible power dissipation P 35 mW; (5)Power dissipation derating; (6)(Ta > 25℃) ΔP/℃ -0.5 mW/℃; (7)Operating temperature range Topr -30 to 85 ℃; (8)Storage temperature range Tstg -40 to 100 ℃; (9)Soldering temperature range (Note 1) Tsol 260 ℃.

Features

tps852 features: (1)Ultra-compact and light surface-mount package: 1.6 x 1.6 x 0.55 mm; (2)Excellent output linearity of illuminance; (3)Little fluctuation in light current and high level of sensitivity 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.); (4)Low supply voltage, making device suitable for battery-powered equipment: VCC = 2.7 V to 5.5 V; (5)Lead(Pb)-Free.
