General Description

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.

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.
