DESCRIPTION

The UAA4713 is a monolithicintegrated circuit in­tended to control triac or relay switch for AC­mains timer applications.Thedevice can be used
in a wide range of industrial and consumer appli­cations as light control, automatic door opening
detector, fire alarm, fluid level control .

The circuit processes the output signal of an infra­red pyroelectric detector which senses tempera­ture changes caused by heat radiation of the hu­manbody.

If the sensor detects a temperature change, a
programmable timer will start and switch a lamp
or other loads to themains.

A further input for a photo-resistivesensor allows
to program circuit operation depending on the
day-lightintensity.

Internal circuits avoid false triggering of the exter­nal actuators. (see functional diagram).
