Smoke and heat detector

Smoke and heat detector design resources and block diagrams


Wireless connectivity, audio and multiple sensing (temp, humidity and motion) are new trends in smoke and heat detectors. Our integrated circuits and reference designs help you solve challenges from emerging standards and technologies such as photoelectric, ionization, and heat/CO detection.

Smoke and heat detector designs often require:

  • Sensors at an optimized BOM cost that meet industry standards
  • 10 year battery life with increased functionality
  • Distinction between real and nuisance sources of smoke
  • Various input power sources with a wide supply voltage range
  • Efficient sensing of obstructions relative to detector placement
