Description

The RE46C143E16F is a low power CMOS photoelectric type smoke detector IC. It is designed to provide all the required features for a photoelectric type smoke detector with minimal external components. The circuit incorporates a gain selectable photo amplifier for use with an infrared emitter/detector pair. It also includes an internal oscillator that strobes power to the smoke detection circuitry to minimize standby current. When smoke is sensed, the detection rate is increased to verify an alarm condition. The RE46C143E16F is designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268.
