MC145018 Datasheet | Freescale Semiconductor

Archive Information Archive Information Archived by Freescale Semiconductor, Inc., 2009 Freescale Semiconductor Technical Data 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 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. Features - Ionization Type with On-Chip FET Input parator - Piezoelectric Horn Driver - Guard Outputs on Both Sides of Detect Input - Input-Protection...
