TPS853

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.

This photo-IC can be used as the power-saving control for domestic

appliances or for backlighting for displays in cellular phones.

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

consumption of the system.

• Ultra-compact and light surface-mount package:

2.0 mm × 2.1 mm × 0.7 mm

• Excellent output linearity of illuminance

• Little fluctuation in light current and high level of sensitivity:

TOSHIBA

0-2D1A

Weight: 0.0054 g (typ.)

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 in light current

• 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

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even

if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum

ratings and the operating ranges.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook

(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test

report and estimated failure rate, etc).

Note 1: The reflow time and the recommended temperature profile are shown in the section entitled Handling

Precautions.
