Alpha and Omega Semiconductor Limited (AOS), based in United States, has announced the launch of its AOZ17517QI series, a 60A eFuse in a compact 5mm x 5mm QFN package. This latest offering has been specifically optimized for 12V power rails in servers, data centers, and telecom infrastructure, catering to the escalating demand for compact and high-efficiency protection solutions.
According to Alpha and Omega Semiconductor Limited (AOS) the new 60A eFuse will feature industry-leading performance and low 0.65 milliohm on-resistance along with additional features optimized for server power rails.
In addition to this, all critical power rails are monitored and protected by an eFuse device to protect the main power bus from interruption due to abnormal load under fault conditions.
The AOZ17517QI series’ MOSFET will offers low RDS(ON) (0.65mohm) that isolates the load from the input bus when the eFuse is off. These devices are designed to integrate accurate analog current and voltage monitoring signals, and designers can also use multiple eFuse devices in parallel for higher current applications.
Apart from this, the AOZ17517QI series will be immediately available in production quantities with a lead time of 14 weeks. The unit price for AOZ17517QI starts at USD 1.8 in 1,000-unit quantities.
However, this approach is being consistently lowered in favor of a more compact solution offered by an eFuse. The ability of AOS’ is to combine our advanced TrenchFET technology with industry-leading IC technology enables us to provide a more compact, robust eFuse product solution that is optimized for the needs of today’s server designs,”.
Executive Statement
According to the James Wang, Power IC Marketing Manager at AOS, high-reliability systems such as servers and other types of telecom applications have a critical requirement for input bus protection. Traditional protection methods have used a hot-swap controller and an external discrete FET to meet these needs.
