Technical Data  
Photoelectric Smoke  
Detector IC with I/O  
MC145010  
The CMOS MC145010 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.  
PHOTOELECTRIC SMOKE  
DETECTOR IC WITH I/O  
The variable-gain photo amplifier allows direct interface to IR detectors  
(photodiodes). Two external capacitors, C1 and C2, C1 being the larger, determine  
the 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 during  
push button test. During standby, the special monitor circuit which periodically  
checks for degraded chamber sensitivity uses high gain, also.  
The I/O pin, in combination with VSS, can be used to interconnect up to 40 units  
for 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/O  
driver, thereby signaling remote smoke to the interconnected units. Additionally, the  
I/O pin can be used to activate escape lights, enable auxiliary or remote alarms,  
and/or initiate auto-dialers.

CASE 648-08  
While in standby, the low-supply detection circuitry conducts periodic checks  
using a pulsed load current from the LED pin. The trip point is set using two external  
resistors. 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 LED  
flash indicates a low-supply condition. A beep occurring half-way between LED  
flashes indicates degraded chamber sensitivity. A low-supply condition does not  
affect the smoke detection capability if VDD ≥ 6 V. Therefore, the low-supply  
condition and degraded chamber sensitivity can be further distinguished by  
performing a push button (chamber) test.
