RE46C127
CMOS Ionization Smoke Detector ASIC with Interconnect and Timer Mode Product Specification
General Description
The RE46C127 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.
A 2/3 duty cycle continuous horn pattern is used for the alarm condition.
An interconnect pin allows multiple detectors to be connect...
