RE46C122 - CMOS Ionization Smoke Detector ASIC

Datasheet Summary

Description

The RE46C122 is low power CMOS ionization type smoke detector IC.

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. An internal 10 minute timer allows for a separat.

R&E International A Subsidiary of Microchip Technology Inc. RE46C122 CMOS Ionization Smoke Detector ASIC with Interconnect and Timer Mode Product Specification General Description The RE46C122 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.
