RE46C165/6/7/8

CMOS Photoelectric Smoke Detector ASIC

with Interconnect, Timer Mode and Alarm Memory

Features

Description

• Temporal Horn Pattern or Continuous Tone

• Alarm Memory

The RE46C165/6/7/8 devices are low-power, CMOS

photoelectric type, smoke detector ICs. With minimal

external components, these circuits will provide all the

required features for a photoelectric type smoke

detector.

• Sensitivity Control Times:

- 9 minutes (RE46C165/6)

- 1.2 minutes (RE46C167/8)

Each design incorporates a gain selectable photo

amplifier for use with an infrared emitter/detector pair.

• I/O Filter and Charge Dump

• Interconnect up to 40 Detectors

• Internal Power-on Reset

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.

• >2000V ESD Protection (HBM) on All Pins

• Low Quiescent Current Consumption (<8 µA)

• Internal Low Battery Detection and Chamber Test

• RoHS Compliant Lead-Free Packaging

A check for a low battery condition and chamber

integrity is performed every 43 seconds when in

standby. The temporal horn pattern supports the

NFPA 72 emergency evacuation signal.

An interconnect pin allows multiple detectors to be

connected so when one unit alarms, all units will sound.

A charge dump feature will quickly discharge the

interconnect line when exiting a local alarm. The

interconnect input is also digitally filtered.

An internal timer allows for single button, push-to-test

to be used for a reduced sensitivity mode.

An alarm memory feature allows the user to determine

if the unit has previously entered a local alarm

condition.

Utilizing

low-power

CMOS

technology,

the

RE46C165/6/7/8 was designed for use in smoke

detectors that comply with Underwriters Laboratory

Specification UL217 and UL268.
