BL5980 Low Voltage Photoelectric Smoke Detector ASIC

BL5980 Low Voltage Photoelectric Smoke Detector ASIC

The BL5980 is a low power, low voltage photoelectric type smoke detector IC. With minimal external components, this circuit will provide all the required features for a photoelectric-type smoke detector. A check for a low battery condition is performed every 86 seconds, and chamber integrity is test.
