BQ24161B: BQ24161B Internal and External FETs

Matt Mottier
Prodigy 210 points
Part Number: BQ24161B

When using an external FET on the BQ24161B (or other variations), I assume that the internal FET is fully operational and in parallel to the external FET, with current splitting between the internal and external FETs.  I would also assume the RDSON of the battery FET path would be approximately the parallel RDSON of the internal and external FETs.

Please confirm or correct my assumptions.
