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.
The UAA4713 is a motion detector interface intended to control triac or relay switch for AC-mains timer applications. It processes the output signal of an infrared pyroelectric detector which senses temperature changes caused by heat radiation, as well as a photo-resistive sensor input for daylight intensity.
| Operating Temperature Range | -25 to 85 °C |
|---|---|
| Supply Current (Operative) | +0.7 mA |
| Package Type | DIP-14 |
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 UAA4713 can operate at temperatures up to 85 °C.
A second timer provides a 600ms dead time to prevent retriggering.
The total power dissipation is limited to 650 mw when the junction temperature is 85°C.
