I have a question about NX20P3483UK .

When the chip works in the Dead Battery Mode,

In the case of external USB 5V power supply, whether the chip is still charging the board at this time.

If charging, what is the charging path, or what is the process?

In dead battery mode,the HV sink active with short circuit protection once current above 10A.

So about the charger current depend on the charger IC not this load switch.

Hi，

Thank you for your reply。I get it, but I want to confirm it again.

According to the description of the datasheet，“NX20P3483UK automatically closes HV sink path ” means HV sink path active, is that right ?

Yes,'close' means switch on,'open' means switch off.
