Low-Power CMOS
Ionization Smoke Detector IC with
Interconnect and Temporal
Horn Driver
The MC145018, when used with an ionization chamber and a small number
of external components, will detect smoke. When smoke is sensed, an alarm is
sounded via an external piezoelectric transducer and internal drivers. This circuit
is designed to operate in smoke detector systems that comply with UL217 and
UL268 specifications.
