AOS launches 60A eFuse for data center power protection

SUNNYVALE, Calif. - Alpha and Omega Semiconductor Limited (Nasdaq:AOSL), a semiconductor company with a market capitalization of $752 million and annual revenue of $696 million, announced Tuesday the release of its AOZ17517QI series, a 60A eFuse designed for 12V power rails in servers, data centers, and telecom infrastructure. According to InvestingPro data, the company maintains a strong financial position with more cash than debt on its balance sheet and a healthy current ratio of 2.58.

The new eFuse features a low 0.65 milliohm on-resistance in a compact 5mm x 5mm QFN package. The device continuously monitors current flowing through the power switch and limits current to the maximum allowed when exceeded. If high current load persists, the switch turns off to protect downstream components.

AOS combined its IC technology with its latest high SOA Trench MOSFET to create the new product. The AOZ17517QI series includes accurate analog current and voltage monitoring signals and allows multiple devices to operate in parallel for higher current applications.

"AOS’s ability to combine our advanced TrenchFET technology with our 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," said James Wang, Power IC Marketing Manager at AOS, in a press release statement.

The device operates in a 4.5V to 20V range with a 27V absolute maximum rating. Protection features include programmable over current protection, short-circuit protection, under-voltage lock-out, over-voltage clamp, thermal shutdown protection, programmable soft-start, and startup SOA management.

The AOZ17517QI series is available in production quantities with a 14-week lead time. Pricing starts at $1.8 in 1,000-unit quantities.
