PYQ 1548 Quad-Element Low-Power DigiPyro

With a mere 1.8 V power requirement, Excelitas offers the first real low-power enhanced DigiPyro® Series. The PYD 1548 is a fully integrated, Quad-Element Detector. That DigiPyro offers added features and low-current power consumption for extended remote motion detection in battery operated devices.

The Low-Power DigiPyro PYQ 1548 works at the new industry-leading standard of 1.8 V supply voltage and significantly reduced supply current. The power requirements of the system level can be further reduced with the wake-up/sleep feature of this detector series, which also promotes power efficiency and extends service life. This Pyrodetector Series is ideal for prolonged battery operated motion detection. A selectable band-pass function and pulse count option further compliment the full functionality of this device. That sensor is also available with smaller elements of 0.8x0.8 mm². Small elements are suitable for compact lenses and short detection distances.  

Features 

  • Integrated digitization 
  • Motion detection unit with interrupt function 
  • Low-power consumption of only 3 µA at 1.8 V 
  • High-responsivity ceramic pyroelectric elements 
  • Dual detector with 1 × 1 mm² (0.8 x 0.8 mm²) elements 
  • 119° (140°) Field-of-view  
  • TO-5 metal housing for high EMI immunity 
  • Optimal for easy integration into product designs 

Applications 

  • Mid (Short)-range motion detection (with lens) 
  • Energy saving applications 
  • Intrusion alarms 
  • Ceiling mounting applications 
  • Battery operation
