RE46C141
CMOS Photoelectric Smoke Detector ASIC with Interconnect Product Specification
General Description
The RE46C141 is low power 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 for 100us every 8.
1 seconds to keep 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 ...
