Microchip Technology announced what it asserts are the industry’s first Ion and photo smoke-detector ICs to offer alarm memory. The low-power RE46C162/3 Ion and RE46C165/6/7/8 (RE46C16X) photo smoke-detector ICs allow users to quickly determine which detector in an interconnected loop triggered an alarm. The ICs’ low energy use enables smoke detectors with a battery life of 10 years, according to the company, and an interconnect filter enables a connection to other devices, such as CO detectors. Homes often have interconnected smoke detectors, to remotely alert the resident about remote smoke events. A charge-dump feature allows the alarm on all interconnected devices to stop sooner.
