TPS2540 2.4A current limit setting at divider mode

Other Parts Discussed in Thread: TPS2543, TPS2540

Could you let me know the max current limit setting value at divider mode, please?
My customer is looking for USB Charging Port Power Switch and Controller which can do 2.4A current limit setting with divider mode.

I know TPS2543 can set only 1 or 2.1A at divider mode.

Best regards,
Shimizu

Do you mean the TPS2540 (not TPS2450)?

The recommended operating rating is 2.5A for both TPS2540 and TPS2543 is 2.5A continuous so set the ILIM resistor accordingly for the desired application current limit.
