MC145017 Datasheet | Freescale Semiconductor

.. Freescale Semiconductor Technical Data MC145017 Rev. 6.0, 3/2007 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 ponents, 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 ply with UL217 and UL268 specifications.
