DESCRIPTION
The UAA4713 is a monolithicintegrated circuit in-
tended to control triac or relay switch for AC-
mains timer applications.Thedevice can be used
in a wide range of industrial and consumer appli-
cations as light control, automatic door opening
detector, fire alarm, fluidlevel 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-
manbody.
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-resistive sensor allows
to program circuit operation depending on the
day-lightintensity.
Internal circuits avoid false triggering of the exter-
nal actuators. (see functionaldiagram).
