Device Overview

Summary

The RE46C200 is a next generation 9-volt, 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 programmable feature set provides a highly flexible means of designing a smoke detector with different features using a single IC.  The design incorporates a gain selectable integrating photo amplifier for use with an infrared emitter/detector pair.  An internal oscillator strobes power to the smoke detection circuitry for 5ms every 10 seconds to keep standby current to a minimum. The RE46C200 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268.
