, 2009 Freescale Semiconductor Technical Data Photoelectric Smoke Detector IC with I/O For Line-Powered Applications The CMOS MC145011 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 piezoelectric transducer.
The variable-gain photo amplifier allows direct interface to IR detectors (photodiodes).
