Microchip Technology has introduced the Ion and photo smoke detector ICs that are first of a kind in the industry. The new smoke detector ICs feature alarm memory. The RE46C162/3 models are ion smoke detector ICs, and the RE46C165/6/7/8 models are photo smoke detector ICs.
These ICs help users to determine quickly which sensor in the loop had triggered the alarm. As they consume low energy, it offers a battery life of about 10 years. The smoke detector ICs feature an interconnect filter that allows them to be connected with other devices for instance CO detectors.

The unique alarm memory feature of the RE46C16X ICs facilitates easy identification of the smoke detector that raised the false alarm. This helps to significantly reduce the costs related to installing and troubleshooting of such smoke detectors. With a charge-dump feature, the ICs also enable the alarm to be stopped quickly.
The marketing vice president of Analog and Interface Products division at Microchip, Bryan J. Liddiard, said that the new alarm memory product demonstrates the company’s commitment towards the smoke detector market.
