MC145017 Ionization Smoke Detector IC with Temporal Pattern Horn Driver
Low–Power CMOS-------
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. Ionization Type with On–Chip FET Input Comparator Piezoelectric Horn Driver Guard Outputs on Both Sides of Detect Input Input–Production Diodes on the Detect Input Low–Battery Trip Point, Internally Set, can be Altered Via External Resistor Detect Threshold, Internally Set, can be Altered Via External Resistor Pulse Testing for Low Battery Uses LED for Battery Loading Comparator Outputs for Detect and Low Battery Internal Reverse Battery Protection Supports NFPA 72, ANSi 53.41, and ISO 8201
Audible Emergency Evacuation Signals
MAXIMUM RATINGS* (Voltages referenced to VSS) Maximum Ratings are those values beyond which damage to the device may occur.
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal
precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation
it is recommended that Vin and Vout be constrained to the range VSS (Vin or Vout) VDD.
