RE46C145  
CMOS Photoelectric Smoke Detector ASIC with Interconnect  
and Timer Mode  
Features:  
General Description:  
• Internal Power On Reset  
The RE46C145 is a low-power, CMOS photoelec-  
tric-type smoke detector IC. With minimal external  
components, this circuit will provide all the required fea-  
tures for a photoelectric-type smoke detector.  
• Low Quiescent Current Consumption  
• ESD Protection on all Pins  
• Interconnect up to 40 Detectors  
• 10 Minute Timer for Sensitivity Control  
Temporal Horn Pattern  
The design incorporates a gain-selectable photo  
amplifier for use with an infrared emitter/detector pair.  
An internal oscillator strobes power to the smoke  
detection circuitry for 100 µs every 10 seconds to keep  
standby current to a minimum. If smoke is sensed, the  
detection rate is increased to verify an Alarm condition.  
A High Gain mode is available for push button chamber  
testing.  
• Internal Low Battery and Chamber Test  
• Compatible with Allegro A5366  
• Alternate Diagnostic Mode  
• UL Recognized per File S24036  
In diagnostic mode, the photo amplifier output is avail-  
able on pin 15 for production calibration of the photo  
chamber.  
When in Standby, a check for a low battery condition  
and chamber integrity is performed every 43 seconds.  
The temporal horn pattern supports the NFPA 72  
emergency evacuation signal.  
An interconnect pin allows multiple detectors to be con-  
nected such that when one units alarms, all units will  
sound.  
An internal 10 minute timer can be used for a reduced  
sensitivity mode.  
The RE46C145 is recognized by Underwriters  
Laboratories for use in smoke detectors that comply  
with specification UL217 and UL268.
