New 30V P-Channel PowerTrench(R) MOSFET technology from Fairchild Semiconductor International (NYSE:FCS) features enhanced rugged-gate technology with 25V gate-to-source maximum rating, making it ideal for operation in battery charger and disconnect applications for notebook computers and other portable electronics.

In these applications, input voltages typically are as high as 22V. Prior to this innovation, P-Channel MOSFET maximum gate ratings were no higher than 20V. Because of this, a separate gate protection zener diode was used with the MOSFET. The higher VGS(max) rating eliminates the need for this added component for high-side applications.

The new P-Channel MOSFET also features lower RDS(on), lower gate charge, and faster switching characteristics than comparable MOSFETs. These characteristics make them ideal for battery charging and other DC/DC applications. Jon Klein, director of Business Development for Fairchild said, "The FDS6679, for example, features the lowest RDS(on) 30V P-Channel in an SO-8 package available in the industry. These MOSFETs are easier and safer to drive, resulting in higher overall efficiencies for DC/DC power supply designs."

Besides notebook charger circuits and battery power management (charger and battery disconnect), the new P-Channel family can be used in disk storage RAID (Redundant Array of Independent Disks) applications as the hot-swap switch.

Fairchild's new, rugged gate 30V P-Channel product line is available in a variety of package types, SO-8, TSSOP-8, SuperSOT(TM)-3 and SuperSOT(TM)-6.
