SEMICONDUCTOR TECHNICAL DATA

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.

P SUFFIX

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 pushbutton test. During standby, the special monitor circuit

which periodically checks for degraded chamber sensitivity uses high gain also.

PLASTIC DIP

CASE 648–08

The I/O pin, in combination with V , 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.

DW SUFFIX

SOIC PACKAGE

CASE 751G–03

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 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
