Technical Data

Photoelectric Smoke Detector IC with

I/O and Temporal Pattern Horn Driver

MC145012

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

piezoelectric transducer.

DETECTOR IC WITH I/O AND

TEMPORAL PATTERN

HORN DRIVER

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 V_SS, 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.

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 MC145012 can be a 9.0 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 or chirp occurring halfway between

LED flashes indicates degraded chamber sensitivity. A low-supply condition does

not affect the smoke detection capability if V_DD≥ 6.0 V. Therefore, the low-supply

condition and degraded chamber sensitivity can be further distinguished by

performing a push-button (chamber) test.
