UAA4713 Datasheet | STMicroelectronics

DESCRIPTION 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 DIP-14 SO-14 ORDERING NUMBERS: UAA4713DP UAA4713FP 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.
