DESCRIPTION

The UAA4713 is a monolithic integrated circuit in-

tended to control triac or relay switch for AC-

mains timer applications.The device can be used

in a wide range of industrial and consumer appli-

cations as light control, automatic door opening

detector, fire alarm, fluid level control .

The circuit processes the output signal of an infra-

red pyroelectric detector which senses tempera-

ture changes caused by heat radiation of the hu-

man body.

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 exter-

nal actuators. (see functional diagram).

This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
