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 × 2.1 × 0.7 mm

• Excellent output linearity of illuminance

• Little fluctuation in light current and high level of sensitivity

: 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

• Lead(Pb)-Free

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.
