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).
