Ionization Smoke-Detector IC With Programmable Calibration and Feature Selection

Wed, 11/09/2011 - 12:18pm
smoke detector ICMicrochip Technology Inc. announced the RE46C180 — said to be the world’s first ionization smoke-detector IC with programmable calibration and programmable feature selection, and the first with horn synchronization and auto alarm locate. This ASIC also has expanded options for implementing hush operation, and more options for interconnect operation — including with carbon-monoxide detectors. These features enable designers to develop and manufacture a broad range of residential and commercial smoke detectors using a single IC and PCB. Programmable calibration reduces component counts and makes it easier to set up smoke detectors during manufacturing. The RE46C180’s programmable features allow one IC to be used for multiple smoke-detector models, including models with different battery types, horn patterns and other features. Horn synchronization enables designers to easily synchronize temporal horn patterns in multiple-detector systems. Auto alarm locate enables the users of multiple-detector systems to quickly identify the smoke detector causing the alarm and assess the threat.
