RE46C144  
CMOS Photoelectric Smoke Detector ASIC with Interconnect  
and Timer Mode  
Features  
General Description  
• Internal Power-On Reset  
The RE46C144 is a low-power, CMOS photoelectric-  
type smoke detector IC. With minimal external  
components, this circuit will provide all the required  
features 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  
• 75% Duty Cycle Horn Pattern  
• Internal Low Battery and Chamber Test  
• Compatible with Allegro A5358  
• UL Recognized per File S24036  
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.  
A check for a low-battery condition and chamber  
integrity is performed every 43 seconds, when in  
Standby. The alarm horn pattern utilizes a 75% duty  
cycle.  
An interconnect pin allows multiple detectors to be  
connected such that when one units alarms, all units  
will sound.  
An internal 10 minute timer can be used for a reduced  
sensitivity mode.  
The RE46C144 device is recognized by  
Underwriters Laboratories for use in smoke  
detectors that comply with specification UL217 and  
UL268.
