BQ24616: Max charge current..20A or10A

JPAlleyne

Part Number: BQ24616
Other Parts Discussed in Thread: BQ24618

I'm not sure what the max charge current it... on the page: http://www.ti.com/power-management/battery-management/charger-ic/products.html#p1152=6;8&p1153max=15;20&p2656max=28;30 it says that these parts are 20A max charge current... On the datasheet it says max charge current is 10A... Which one is correct?

Thanks,

Hello JP,
The current is regulated by the voltage across the current sense resistor. It is 10A with a 10mOhm sense resistor. We typically recommend 10A due to thermal performance of the external FETs. However, 20A is achievable with proper thermal design and a 5mOhm sense resistor.

Does that apply to the bq24618 as well?
