RE46C126
CMOS Ionization Smoke Detector ASIC with Interconnect
Product Specification
General Description
The RE46C126 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. . A 2/3 duty cycle continuous horn pattern is
used for the alarm condition.
An interconnect pin allows multiple detectors to be
connected such that when one unit alarms all units will
sound.
Although this device was designed for smoke detection
utilizing an ionization chamber it can be used in a
variety of security applications.
Utilizing low power CMOS technology the RE46C126
was designed for use in smoke detectors that comply
with Underwriters Laboratory Specification UL217 and
UL268.

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

Notes:
1. Smoke is not sampled when the horn is active. Horn cycle is self completing in local alarm
2. Low battery warning chirp is suppressed in alarm
3. IO Dump active only in local alarm, inactive if external alarm
