  • Smoke Detector IC MC

    Contact NowSmoke Detector IC MC(Smoke Detector IC)MC145010DW D/C:(Smoke Detector IC)MC145010DW Package:(Smoke Detector IC)MC145010DW SOP, 16 Lead SOICW Model Number:(Smoke Detector IC)MC145010DW Type:Drive IC, Smoke Detector Brand Name:Original Brand The MC145010 is an advanced smoke detector component containingsophisticated very-low-power analog and digital circuitry. The IC is used with aninfrared photoelectric chamber. Detection is accomplished by sensing scatteredlight from minute smoke particles or other aerosols. When detection occurs, apulsating alarm is sounded via on-chip push-pull drivers and an externalpiezoelectric transducer. The variable-gain photo amplifier allows direct interface to IR detectors(photodiodes). Two external capacitors, C1 and C2, C1 being the larger, determinethe gain settings. Low gain is selected by the IC during most of the standby state.Medium gain is selected during a local-smoke condition. High gain is used duringpush button test. During standby, the special monitor circuit which periodicallychecks for degraded chamber sensitivity uses high gain, also. The I/O pin, in combination with VSS, can be used to interconnect up to 40 unitsfor common signaling. An on-chip current sink provides noise immunity when the I/O is an input. A local-smoke condition activates the short-circuit-protected I/Odriver, thereby signaling remote smoke to the interconnected units. Additionally, theI/O pin can be used to activate escape lights, enable auxiliary or remote alarms,and/or initiate auto-dialers. While in standby, the low-supply detection circuitry conducts periodic checksusing a pulsed load current from the LED pin. The trip point is set using two externalresistors. The supply for the MC145010 can be a 9 V battery.A visible LED flash accompanying a pulsating audible alarm indicates a local-smoke condition. A pulsating audible alarm with no LED flash indicates a remote-smoke condition. A beep or chirp occurring virtually simultaneously with an LEDflash indicates a low-supply condition. A beep occurring half-way between LEDflashes indicates degraded chamber sensitivity. A low-supply condition does notaffect the smoke detection capability if VDD ≥ 6 V. Therefore, the low-supplycondition and degraded chamber sensitivity can be further distinguished byperforming a push button (chamber) test.Read More
