RE46C165

RE46C165/6/7/8 CMOS Photoelectric Smoke Detector ASIC with Interconnect, Timer Mode and Alarm Memory Features Temporal Horn Pattern or Continuous Tone Alarm Memory Sensitivity Control Times: - 9 minutes (RE46C165/6) - 1.2 minutes (RE46C167/8) I/O Filter and Charge Dump Interconnect up to 40 Detectors Internal Power-on Reset (POR) >2000V ESD Protection (HBM) on All Pins Low Quiescent Current Consumption (<8 µA) Internal Low Battery Detection and Chamber Test RoHS Compliant Lead-Free Packaging Description The RE46C165/6/7/8 devices are low-power, CMOS photoelectric type, smoke detector ICs. With minimal external components, these circuits will provide all the required features for a photoelectric type smoke detector. Each 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 100 µs, every 10 seconds, to keep standby current ...
