RE46C143S16F - Brand New Microchip Technology Sensor and Detector Interfaces
-
General Description
The RE46C143 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 push button chamber testing.
A check for a low battery condition and chamber integrity is performed every 40 seconds when in standby. The alarm horn pattern utilizes a 75% duty cycle.Features
