SUNNYVALE, Calif., Feb. 5, 2015 (GLOBE NEWSWIRE) -- 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 two new MOSFETs optimized for battery protection applications. The AOC2804 and AOC2806 are the latest additions to the AlphaDFN™ package portfolio which takes chip scale packaging to the next level. These devices are specifically targeting one and two cells portable battery pack applications such as those found in the latest smart phones, tablets, media players and wearable devices.

In mobile battery pack applications the protection MOSFET controls charging and discharging of the battery, and is critical to battery life and battery safety. The new generation of devices is optimized with AOS's proprietary power trench technology, which minimizes RSS (source- to-source resistance) in a common-drain MOSFET configuration. For the same dimensions, these new devices can deliver 20% lower resistance, which makes them ideal for conserving battery life. AOC2804, 1.5mm x 1.5mm, is aimed at 22 mΩ max RSS level applications such as feature phones and wearable devices. AOC2806, with slightly larger dimension at 1.7mm x 1.7mm, is a 18 mΩ max RSS device that is best-suited for smart phones. When used in parallel, either device can significantly reduce conduction loss by offering <10 mΩ RSS.
In addition to the silicon technology, the AOC2804 and AOC2806 feature AOS's proprietary AlphaDFN packaging technology encapsulating silicon in a protective molding compound. The resulting product still provides an ultra-thin 0.3mm solution, while providing a more robust structure to solve die chipping and placement issues associated with standard CSP products.
"AOS's new AlphaDFN MOSFETs series deliver a superior solution for battery pack protection. Their low RSS and small chip-scale footprint help designers enhance battery life while saving precious board space. Additionally, the extra layer of protection in the proprietary AlphaDFN package enhances mechanical robustness and reliability," said George Feng, Senior Manager for Product Marketing.
AOC2804 and AOC2806 are all Halogen-Free and RoHS compliant.
