RE46C112
Ionization Smoke Detector IC
Product Specification
General Description
The RE46C112 is an ionization type smoke detector IC.
It is intended for applications using ionization type
chambers to detect smoke. When enabled, VOUT is ¼
of either the DETECT input or VDD depending on the
status of the SELECT input. When the Select input is
allowed to float the circuit is in the low current mode
with only the guard amplifier enabled.
Utilizing low power CMOS technology the RE46C112
was designed for use in smoke detectors that comply
with Underwriters Laboratory Specification UL217.
