Freescale Semiconductor
Technical Data
Freescale Semiconductor, Inc. reserves the right to change the detail specifications, as may be required, to
permit improvements in the design of its products.
Low-Power CMOS
Ionization Smoke Detector IC
with Temporal Pattern Horn Driver
The MC145017, 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.
