DESCRIPTION

DIP-14	SO-14
ORDERING NUMBERS:
UAA4713DP	UAA4713FP

The UAA4713 is a monolithic integrated circuit intended to control triac or relay switch for ACmains timer applications.The device 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 human body.

BLOCK DIAGRAM

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

A further input for a photo-resistive sensor allows to program circuit operation depending on the day-light intensity.

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