MC145012 Datasheet (Freescale Semiconductor) - Photoelectric Smoke Detector IC

MC145012, Photoelectric Smoke Detector IC

Freescale Semiconductor Technical Data Photoelectric Smoke Detector IC with I/O and Temporal Pattern Horn Driver The CMOS MC145012 is an advanced smoke detector component containing sophisticated very-low-power analog and digital circuitry.

The IC is used with an infrared photoelectric chamber.

Detection is accomplished by sensing scattered light from minute smoke particles or other aerosols.

When detection occurs, a pulsating alarm is sounded via on-chip push-pull drivers and an external piez
