Smoke detector IC

7 March 2012 Analogue, Mixed Signal, LSI

New from Microchip is what the company claims to be the world’s first ionisation smoke detector IC with programmable calibration and programmable feature selection, and the first with horn synchronisation and auto alarm locate. The RE46C180 ASIC also has expanded options for implementing hush operation and more options for interconnect operation, including support for 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.

On-chip programmable calibration reduces component counts and eliminates the cost of manual calibration as well as simplifying setup of smoke detectors during manufacturing. Additionally, the programmable features allow one IC to be used for multiple smoke detector models, including models with different battery types, horn patterns and other features.

The RE46C180 also enables manufacturers to provide smoke detector users with additional features. Horn synchronisation enables designers to easily synchronise temporal horn patterns in multiple-detector systems whilst auto alarm locate enables the users of multiple-detector systems to quickly identify the smoke detector causing the alarm and assess the threat.
