LTC4418 Typical current capability

Hi

I am after a device that can control two power paths and switch between them seamlessly.
The highest priority path is the 24Vdc derived from the AC-to-DC power supply.
If this fails then it has to switch to the 24Vdc battery bank.
The switching current can be as high as 25A maximum.

 

Although not specifically mentioned in the data sheet the selection table on the website tells that the
"Typical current capability" is 5A.
I thought with an external MOSFET it should be able to handle more current based on the MOSFET selected.

Why is the typical current capability of 5A mentioned is to do with MOSFET driver capability.

 

Thanks

Diva
