Description

PHOTOELECTRIC SMOKE DET IC 16SOIC
The RE46C140 is low power CMOS photoelectric type smoke detector IC. With minimal external components this circuit will provide all the required features for a photoelectric type smoke detector. The design incorporates a gain selectable photo amplifier for use with an infrared emitter/detector pair. An internal oscillator strobes power to the smoke detection circuitry for 100us every 10 seconds to keep standby current to a minimum. If smoke is sensed the detection rate is increased to verify an alarm condition. A high gain mode is available for push button chamber testing. A check for a low battery condition and chamber integrity is performed every 43 seconds when in standby. The temporal horn pattern supports the NFPA 72 emergency evacuation signal. 2009 © Microchip Technology Inc. DS22179B-page 1 An interconnect pin allows multiple detectors to be connected such that when one units alarms, all units will sound. An internal 10 minute timer can be used for a reduced sensitivity mode. The RE46C140 is recognized by Underwriters Laboratories for use in smoke detectors that comply with specification UL217 and UL268.
