RE46C143E16F  离子烟雾探测器IC

The RE46C143 is 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 100us every 8.1 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 40 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.

The RE46C143 is recognized by Underwriters

Laboratories for use in smoke detectors that comply

with specification UL217 and UL268.
