Description

The A5366 is a low-current BiCMOS circuit providing all of

the required features for a photoelectric type smoke detector.

This device can be used with an infrared photoelectric chamber

to sense scattered light from smoke particles. A networking

capability allows as many as 50 units to be interconnected so that

if any unit senses smoke all units will sound an alarm. Special

features are incorporated in the design to facilitate calibration

and testing of the finished detector. The device is recognized by

Underwriters Laboratories for use in smoke alarms that comply

with Standard UL217, or UL268, per file #S2113.

A variable-gain photoamplifier can be directly interfaced to

an infrared emitter-detector pair. The amplifier gain levels are

determined by two external capacitors and are internally selected

depending on the operating mode. Low gain is selected during

standby and timer modes. During a local alarm, this low gain

is increased (internally) by approximately 10% to reduce false

triggering. High gain is used during pushbutton test and to

periodically monitor the chamber sensitivity during standby.

The internal oscillator and timing circuitry keep standby power

to a minimum by sensing for smoke for only 100

μs

every 10 s.

A special three-stage–speedup sensing scheme is incorporated

to minimize the time to an audible alarm and also to reduce

false triggering. Chamber sensitivity is periodically monitored

and two consecutive cycles of degraded sensitivity are required

for a warning signal (chirp) to occur.

The A5366 is supplied in a 16-pin dual in-line plastic package

(suffix A), and for surface mount, a 16-pin SOICW (suffix

LW). The lead (Pb) free versions (suffix –T) have 100% matte-

tin leadframe plating. The devices are rated for continuous

operation over the temperature range of –25°C to 75°C.
