RE46C152
CMOS Ionization Smoke Detector ASIC with Interconnect, Timer Mode and Tone Select
Product Specification
General Description
The RE46C152 is a 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 Tone input allows for selection of a
temporal pattern or a 2/3 duty cycle continuous tone.
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.
An internal 8 minute timer allows for a separate button
to be used for reduced sensitivity mode. Single button
operation for test and timer mode is also possible.
Although this device was designed for smoke detection
utilizing an ionization chamber it could be used in a
variety of security applications.
Utilizing low power CMOS technology the RE46C152
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.
