Maxim does not recommend nor have we tested under load current conditions of greater than 8A. However the load current only concerns the external FETs. In theory if the external FETs are rated sufficiently for the current being monitored this should be ok. In that case the customer would also need to change Rsense accordingly. For example from 3milliohms to 1.5milliohms in order to adapt the current monitoring range from 3-8A to 6-16A.
