The RE46C141SW16TF is a CMOS photoelectric smoke detector integrated circuit designed by Microchip Technology. This IC provides essential features for a photoelectric smoke detector with minimal external components. It incorporates a gain-selectable photo amplifier and an internal oscillator to minimize standby current, strobing power to the detection circuitry for brief intervals.
Key functionalities include an increased detection rate when smoke is sensed to verify an alarm condition, a high-gain mode for chamber testing, and checks for low battery and chamber integrity. The device supports the NFPA 72 emergency evacuation signal with its temporal horn pattern. An interconnect feature allows multiple detectors to be linked, so an alarm in one unit triggers all connected units.
This smoke detector IC is recognized by Underwriters Laboratories for compliance with UL217 and UL268 specifications. It is available in a 16-SOIC package and is designed for surface mounting. The operating temperature range is -25°C to 75°C, with a low quiescent current consumption of 8 µA.
