MOTOROLA SEMICONDUCTOR TECHNICAL DATA Freescale Semiconductor, Inc. Order this document by MC145018/D MC145018 Low Power CMOS Ionization Smoke Detector IC with Interconnect and Temporal Horn Driver Freescale Semiconductor, Inc 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 smo.

MC145018 Features

* oaded via a 10 mA pulse for 11.6 ms. If the LED is not used, it should be replaced with an equivalent resistor such that the battery loading remains at 10 mA. HYSTERESIS When smoke is detected, the resistor/divider network that sets sensitivity is altered to increase sensitivity. This yields approxi
