UAA4713 is a monolithic integrated circuit intended to control triac or relay switch for AC-mains timer applications. The device can be used in a wide range of industrial and consumer applications such as light control, automatic door opening detector, fire alarm, fluid level control, etc. The circuit processes the output signal of an infrared pyroelectric detector which senses temperature changes caused by heat radiation of the human 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 daylight intensity. Internal circuits avoid false triggering of the external actuators.
