nRF52840 current flow backward function.

[vsion]

Hi everybody!

     I would like to ask the following nRF52840 has the function of preventing current reverse irrigation?

    Or what circuit prevents nRF52840 current from flowing backwards?

     Thanks.

Do you mean reverse polarity protection? In that case, No. But you can add it it your circuit. Here are some suggestions:
