General Description:

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.

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.

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.
