Description
The RE46C190 is not recommended for new designs. 
Please use the RE46C191 for all new designs.

The RE46C190 is a low voltage, low current programmable photoelectric smoke detector IC. This circuit will provide all the required features for a photoelectric smoke detector with minimal external components. Programmable setup, calibration and feature selection are the key to reduced component count and reduced manufacturing costs. The boost regulator insures proper operation of the infrared diode and the piezo horn under low battery conditions. The RE46C190 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268.

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.
