Low-Power CMOS Ionization Smoke Detector with Interconnect and Timer

The MC14568, 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 UL21 • Speed-Up Sampling Rate of 40 ms of Internal Clock Period (Pin 12) After First Detection of Smoke\n• High-Smoke Detection in the “Reduced Sensitivity” Mode\n• Internal and External Smoke Reference Settings\n• Reversed Battery Protection\n• Metal Option to Add Double Chirp atEnd of Reduced Sensitivi;
