RE46C128

CMOS Ionization Smoke Detector ASIC with Interconnect

Product Specification

Features

General Description

•

>1500V ESD Protection (HBM) on all Pins

Guard Outputs for Ion Detector Input

+/-0.75pA Detect Input Current

Internal Reverse Battery Protection

Low Quiescent Current Consumption (<6.5uA)

Available in 16L PDIP or 16L N SOIC

Internal Low Battery Detection

Power Up Low Battery Test

Interconnect up to 40 Detectors

Compatible with Allegro A5364

Pb Free Packaging.

The RE46C128 is low power CMOS ionization type

smoke detector IC. With few external components this

circuit will provide all the required features for an

ionization type smoke detector.

•

An internal oscillator strobes power to the smoke

detection circuitry for 10.5mS every 1.66 seconds to

keep standby current to a minimum. A check for a low

battery condition is performed every 40 seconds when

in standby. The temporal horn pattern supports the

NFPA 72 emergency evacuation signal.

An interconnect pin allows multiple detectors to be

connected such that when one units alarms all units will

sound.

N/C

Although this device was designed for smoke detection

utilizing an ionization chamber it could be used in a

variety of security applications.

LBADJ

N/C

Utilizing low power CMOS technology the RE46C128

was designed for use in smoke detectors that comply

with Underwriters Laboratory Specification UL217 and

UL268.

Maximum Junction Temperature

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress

ratings only and operation at these conditions for extended periods may affect device reliability.

This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used when

handling this product. Damage can occur when exposed to extremely high static electrical charge.
