RE46C190

CMOS Low Voltage Photoelectric Smoke Detector ASIC

with Interconnect and Timer Mode

Features

Description

• Two AA Battery Operation

The RE46C190 is a low power, low voltage CMOS

photoelectric type smoke detector IC. With minimal

external components, this circuit will provide all the

required features for a photoelectric-type smoke

detector.

• Internal Power On Reset

• Low Quiescent Current Consumption

• Available in 16L N SOIC

• Local Alarm Memory

The design incorporates a gain-selectable photo

amplifier for use with an infrared emitter/detector pair.

• Interconnect up to 40 Detectors

• 9 Minute Timer for Sensitivity Control

• Temporal or Continuous Horn Pattern

• Internal Low Battery and Chamber Test

• All Internal Oscillator

An internal oscillator strobes power to the smoke

detection circuitry every 10 seconds, to keep the

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 Infrared Emitter Diode (IRED) driver

• Adjustable IRED Drive current

• Adjustable Hush Sensitivity

A check for a low battery condition is performed every

86 seconds, and chamber integrity is tested once every

43 seconds, when in Standby. The temporal horn pat-

tern supports the NFPA 72 emergency evacuation sig-

nal.

• 2% Low Battery Set Point

An interconnect pin allows multiple detectors to be

connected such that, when one unit alarms, all units will

sound.

An internal 9 minute timer can be used for a Reduced

Sensitivity mode.

Utilizing low power CMOS technology, the RE46C190

was designed for use in smoke detectors that comply

with Underwriters Laboratory Specification UL217 and

UL268.
