Low Power CMOS Photoelectric
Smoke Detector IC
Freescale Semiconductor, Inc., 2007. All rights reserved.
The MC146010 is an advanced smoke detector component containing
sophisticated very-low power analog and digital circuitry. The IC, when used with
an infrared photoelectric chamber and a small number of external components,
detection occurs, a pulsating alarm is sounded via on-chip push-pull drivers and
an external piezoelectric transducer.
The MC146010 provides both audible and visual alarms. Upon sensing a
normal smoke level, both alarms will be activated. It is possible to mute the
audible alarm for approximately eight minutes through the Integrated Mute
Function (IMF), although the LED will continue to flash at a high rate. This feature
is resettable through a pushbutton test. The IMF feature will be overridden by
remote smoke, high smoke level, timeout or reset.
The Alarm memory feature will allow for identification of an alarming detector.
Through a pushbutton test, the LED will flash rapidly if there was a previous
alarm condition detected at the unit.
The variable-gain photo amplifier allows direct interface to IR detector
(photodiode). The gain settings are determined by external capacitors and
compensation resistors. A two stage speed-up is incorporated into the smoke
monitor to minimize time and help reduce false triggering. Further reduction of
false triggering is also addressed with the double sample chamber sensitivity and
double I/O sample.
