Hi Onyx,

BQ28Z610's datasheet of "8.4.2.4 Current measurements" said "external sense resistor (1 mΩ to 3 mΩ)" and BQ27750's datasheet said same thing at "7.4.2.3 Current measurements".
Is this point is difference of these device? Perhaps, Dose BQ28Z610's datasheet explained wrong information?

Best regards,

ok.I mistook the bq28z610 for the bq27742.
The main difference is just the number of cells.
thanks
