New universal, high-speed controller/n-channel power MOSFET driver

Supplier: Richardson Electronics

International Rectifier has introduced the IR5001S universal, high-speed controller/n-channel power MOSFET driver for high-performance, active ORing circuits.

The IC, housed in an SO-8 package, is used with an external MOSFET, replacing a traditional diode ORing to increase efficiency and reduce power dissipation.

Active ORing is a key requirement for many high-end systems requiring maximum up-time, such as carrier-class communication equipment and telecom and datacom system servers.

Compared with typical Schottky diode ORing circuits, a system using the IR5001S and an optimised external MOSFET for the given power level, will reduce onboard power dissipation by up to 85%, and can be made at least 50% smaller than diodes.
