Alpha and Omega Semiconductor Reveals Lowest Rss MOSFET with Advanced CSP Technology
07 October 2016 - 10:16AM
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a
designer, developer and global supplier of a broad range of power
semiconductors and power ICs, today announced the release of
AOC3860, a common-drain 12V dual n-channel MOSFET with the lowest
on-resistance in the product family of 2.15mOhm typical at 4.5V
gate drive. This new device provides further improved
source-to-source resistance, which is a critical factor for smart
phone makers to achieve faster battery charge with a higher
charging current.

The demand for faster charge comes from both the higher capacity
of the battery pack and heavy use of the smart phone with data
ranging from email and web browsing to video streaming. With the
heavy duty use and shorter time for standby, charging has become a
great feature for the newest smart phones. The market is seeing
charging power increase from the traditional 5W to larger wattages
of 15W or 25W, by raising either output voltage or output current.
For battery packs, this always translates to a higher charging
current. A MOSFET is a critical part of the battery charging
circuit, which needs to provide reliable protection with minimum
power loss and temperature rise. The AOC3860 is the latest product
with the best Rss and the smallest mounting size in the AlphaDFN™
family, which is a market-proven product family in the battery
protection module market. The typical Rss is 2.15mOhm with 4.5V
gate voltage, and 2.25mOhm with 3.8V gate voltage. The chip size is
further reduced to a 3.05x1.77mm.
“AOC3860 is a great example of our effort in continuously
improving product performance with AOS process technology and
knowledge base. Compared with our previously released product, we
were able to reduce Rss by 10%, and at the same time significantly
reducing the device size by 14%. This could only be achieved with
our deep understanding of the material, device design, process
control, and improved packaging technology. Battery design
engineers will find this device a good fit for battery packs with
large charging current,” said Lei Feng, Sr. Marketing Director of
MOSFET product line at AOS.
