bq500412 current monitoring requirements

Other Parts Discussed in Thread: BQ500412, BQ500412EVM-584

Hello,

I'm currently working on a wireless transmitter with bq500412 and I would like to ask one question.

It's about the current monitoring requirements. The datasheet says the current sense resistor should be 20mR and
the current shunt amplifier should have a gain of 50 (INA199A1). Nonetheless in BQ500412EVM-584 evaluation module,
the value of the current sense resistor is 40mR with also INA199A1 amplifier.

Which value of the shunt is the correct one?

Thanks,
