NEC Electronics America Inc. introduced the latest additions to its line of low-voltage power management devices (PMDs)the uPA2450B and uPA2451B power MOSFETs.

Developed using NEC Electronics' advanced packaging technology, these dual N- channel MOSFETs promise to deliver very low packaging profiles that enable designers to realize a smaller design footprint. With their thin packaging and several power-saving features, the MOSFETs are suitable for use in portable battery-powered applications such as MP3 players, mobile wireless devices, Li-ion battery packs and glucose meters.

"Portable digital devices continue to capture the interest of many consumers who also are looking to gain as much battery performance as possible from these devices," said Bart Ladd, GM of standard solutions strategic business unit, NEC Electronics America. "With one of the industry's lowest on-state resistances and one of the industry's thinnest packages, the new uPA2450B and uPA2451B power MOSFETs offer designers a proven, leading-edge solution that reduces both form factor and power consumption to meet the stringent demands of the consumer electronics market."

The new devices are manufactured in NEC Electronics' CMOS 4 process technology to enable a higher conversion efficiency and smaller cell. With an on-state resistance of 12.5 milliohms (typical) at a 4.5V gate drive, and VDSS from 20V to 30V, the new devices are able to extend battery life for portable applications. Integrated gate-protection diodes provide lower overall system costs and smaller form factor. In addition, said the company, at 2.1-by-5.1-by-0.8mm, the new devices feature one of the thinnest packages available in the industry.

Both power MOSFETs are already available in production quantities, with prices starting at 25 cents each in low volumes. Pricing and availability are subject to change.
