Description
www.DataSheet4U.com R&E International RE46C128 CMOS Ionization Smoke Detector ASIC with Interconnect Product Specification General Description The RE46C128 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. The temporal horn pattern supports the NFPA 72 emergency evacuation signal. 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 RE46C128 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268. Features >1500V ESD Protection (HBM) on all Pins Guard Outputs for Ion Detector Input +/-0.75pA Detect Input Current Internal Reverse Battery Protection Low Quiescent Current Consumption (<6.5uA) Available in 16L PDIP or 16L N SOIC Internal Low Battery Detection Power Up Low Battery Test Interconnect up to 40 Detectors Compatible with Allegro A5364 Available in Standard Packaging or RoHS Compliant Pb Free Packaging.
