    RE46C165/6/7/8
    CMOS Photoelectric Smoke Detector ASIC
    with Interconnect, Timer Mode and Alarm Memory
    Features Description Temporal Horn Pattern or Continuous Tone Alarm Memory Sensitivity Control Times:
    -9 minutes (RE46C165/6)
    -1.2 minutes (RE46C167/8) I/O Filter and Charge Dump Interconnect up to 40 Detectors Internal Power-on Reset (POR) >2000V ESD Protection (HBM) on All Pins Low Quiescent Current Consumption (<8 ВµA) Internal Low Battery Detection and Chamber Test RoHS Compliant Lead-Free Packaging The RE46C165/6/7/8 devices are low-power, CMOS
    photoelectric type, smoke detector ICs. With minimal
    external components, these circuits will provide all the
    required features for a photoelectric type smoke
    detector.
    Each design incorporates a gain-selectable photo
    amplifier for use with an infrared emitter/detector pair.
    An internal oscillator strobes power to the smoke
    detection circuitry for 100 Вµs, every 10 seconds, to
    keep standby current to a minimum. If smoke is
    sensed, the detection rate is increased to verify an
    alarm condition. A High-Gain mode is available for
    push button chamber testing.
    A check for a low battery condition and chamber
    integrity is performed every 43 seconds when in
    standby. The temporal horn pattern supports the
    NFPA 72 emergency evacuation signal.
    An interconnect pin allows multiple detectors to be ...
