The reference design contains four IRF6609 20V, 2mOhm DirectFETTM MOSFETs in parallel to create a 0.5mOhm effective RDS(on) for a high efficiency ORing circuit with fast fault detection and reaction time of 130ns.
The "FET Check" feature is enabled in this reference design, and allows real-time"FET-good" checking for extra fault protection and the highest possible reliability for high power systems.
Active ORing is a key efficiency requirement for many high-end systems requiring maximum up-time, such as carrier-class communication equipment, telecom and datacom system servers. IR's IR5001S IC is ideal for applications such as high reliability server and storage systems where "N+1" redundant power supplies feed into a central load.
