5A eFuse provides industry-leading performance
with low 20mΩ on-resistance for server applications
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a
designer, developer, and global supplier of a broad range of power
semiconductors, power ICs, and digital power products, today
announced the release of our initial eFuse product for sub-power
rails in server applications. The AOZ18101DI series are 5A eFuse in
a compact 3mm x 3mm DFN package. The new products use AOS’s
advanced co-packaging technology, combining a high-performance IC
with protection features and our latest high SOA Trench MOSFET. The
new devices offer low RDS(ON) (20mohm) back-to-back MOSFETs to
isolate the load from the input bus when the eFuse is off.

Due to high-reliability requirements for server products, 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 eFuse continuously monitors the
current flowing through the power switch. If the current is higher
than the set limit, the switch will limit the current to the
maximum allowed. If the high current load persists, the switch will
eventually turn off, protecting downstream loads from damage, thus
acting as a fuse.
AOZ18101DI-01 and AOZ18101DI-02 integrated True Reverse Current
Blocking (TRCB) for the fault conditions that the power rail at
VOUT is higher than the main bus at VIN, allowing no reverse
current. Control for external blocking FET is also available for
designs already in production by offering a drop-in replacement to
existing eFuse products requiring external FETs to implement the
TRCB feature. For loads with high inductive kickback such as hard
disc drive, and server fans, the AOZ18101DI-03 and AOZ18101DI-04
has this TRCB feature disabled to avoid shut down of the input
power bus due to a reverse current. All devices feature startup SOA
management and other protections allowing for glitch-free power-up
of the system or hot plug into the 12V backplane.
“High-reliability systems such as servers and storage require
input bus protection. Traditional designs use a hot-swap controller
and an external discrete FET. Still, this solution is increasingly
dropped in favor of a more compact solution offered by an eFuse.
AOS’s ability to combine TrenchFET technology with leading IC
design enables compact, robust eFuse products,” said Peter Cheng,
Power IC Senior Marketing Director at AOS.
