1 / 42 page 2010 Microchip Technology Inc. DS22271A-page 1 RE46C190 Features • Two AA Battery Operation • Internal Power On Reset • Low Quiescent Current Consumption • Available in 16L N SOIC • Local Alarm Memory • Interconnect up to 40 Detectors • 9 Minute Timer for Sensitivity Control • Temporal or Continuous Horn Pattern • Internal Low Battery and Chamber Test • All Internal Oscillator • Internal Infrared Emitter Diode (IRED) driver • Adjustable IRED Drive current • Adjustable Hush Sensitivity • 2% Low Battery Set Point Description The RE46C190 is a low power, low voltage 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 every 10 seconds, to keep the 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 is performed every 86 seconds, and chamber integrity is tested once every 43 seconds, when in Standby. The temporal horn pat- tern supports the NFPA 72 emergency evacuation sig- nal. An interconnect pin allows multiple detectors to be connected such that, when one unit alarms, all units will sound. An internal 9 minute timer can be used for a Reduced Sensitivity mode. Utilizing low power CMOS technology, the RE46C190 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268.
