Microchip unveils industry’s first ion and photo smoke-detector ICs with alarm memory
		Microchip has announced the industry’s first Ion and photo smoke-detector ICs to offer alarm memory.  The low-power power RE46C162/3 Ion and RE46C165/6/7/8 (RE46C16X) photo smoke-detector ICs make it easy 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, and an interconnect filter enables a connection to other devices, such as CO detectors.

Key Facts:

• Six new, dedicated single-chip solutions enable smarter ‘networked’ alarms
• Low power technology delivers 10years+ service from a single battery
• Alarm Memory feature greatly reduces impact of ‘nuisance tripping’

Homes often have interconnected smoke detectors, to remotely alert the resident about remote smoke events.  When an alarm is falsely triggered, also known as “nuisance tripping,” it is difficult to determine which smoke detector set off the alarm.  The alarm-memory feature available on the RE46C16X ICs enables the detector that caused the fault to be easily identified, which greatly reduces costs associated with installing and troubleshooting these types of smoke-detector systems.  A charge-dump feature allows the alarm on all interconnected devices to stop sooner.

Microchip already offers a broad line of PIC® microcontrollers (MCUs), horn drivers, other smoke-detector ICs, signal-chain and power-management products, providing complete smoke-detector solutions for residential devices to programmable commercial devices.

The six members of the RE46C16X IC family are available in 16-pin PDIP and SOIC 150/300 packages.  For further information, click here.
