Microchip has launched 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 ten years, and an interconnect filter enables a connection to other devices, such as CO detectors. Homes often...
Synchronous rectification drivers
ON Semiconductor releases energy efficient rectification drivers for consumer applications. The NCP4303A and NCP4303B are full featured synchronous rectification controller and driver ICs targeted at use in Switch Mode Power Supplies (SMPS) for applications such as ATX power supplies, flat screen televisions, high power AC-DC adapters, and gaming consoles. Their features provide an efficient and flexible solution for secondary side rectification in SMPS. “The pressure being...
