com R&E International RE46C129 CMOS Ionization Smoke Detector ASIC with Interconnect Product Specification General Description The RE46C129 is low power CMOS ionization type smoke detector IC.
With few external components this circuit will provide all the required features for an ionization type smoke detector.
An internal oscillator strobes power to the smoke detection circuitry for 10.
5mS every 1.
66 seconds to keep standby current to a minimum.
A check for a low battery condition is performed every 40 seconds when in standby.
An interconnect pin allows multiple detectors to be connected such that when one units alarms all units will sound.
Although this device was designed for smoke detection utilizing an ionization chamber it could be used in a variety of security applications.
Utilizing low power CMOS technology the RE46C129 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268.
