BQ25720: Input current limit

switch

Part Number: BQ25720

Tool/software:

Hi ti team，

In the new project, Bq25720 is being used. The customer requires that the adapter should provide more than 12A current when there is no battery, but the input current limit of Bq25720 is 10A. May I ask if I can reduce the sense resistor to increase the input current limit?

Unfortunately, The BQ25720 is not capable of changing the input sense resistor to support greater than 10A input current. The only option I see to get this high input current is to disable IINDPM.
