R&E International A Subsidiary of Microchip Technology Inc. RE46C121 CMOS Ionization Smoke Detector ASIC with Interconnect Product Specification Features General Description Guard Outputs for Ion Detector Input The RE46C121 is low power CMOS ionization type +/-0.75pA Detect Input Current smoke detector IC. With few external components this Internal Reverse Battery Protection circuit will provide all the required features for an ionization type smoke detector. Internal Low Battery Detection Low Quiescent Current Consumption (<6.5uA) An internal oscillator strobes power to the smoke Available in 16L PDIP or 16L N SOIC detection circuitry for 10.5mS every 1.66 seconds to ESD Protection on all Pins keep standby current to a minimum. A check for a low Interconnect up to 40 Detectors battery condition is performed every 40 seconds when Compatible with MC145018 in standby. The temporal horn pattern supports the UL Recognized per File S24036 NFPA 72 emergency evacuation signal. Available in Standard Packaging or RoHS Complaint Pb Free Packaging An interconnect pin allows multiple detectors to be connected such that when one unit alarms all units will Pin Configuration sound. Although this device was designed for smoke detection DETCOMP GUARD2 1 16 utilizing an ionization chamber it can be used in a variety of security applications. IO DETECT 2 15 LBADJ GUARD1 The RE46C120 is recognized by Underwriters 3 14 Laboratories for use in smoke detectors that comply STROBE VSEN 4 13 with specification UL217 and UL268.
