https://devzone.nordicsemi.com/f/nordic-q-a/37183/nrf52840-current-flow-backward-functionHi 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.en-USTelligent Community 13Mon, 06 Aug 2018 08:05:11 GMThttps://devzone.nordicsemi.com/thread/142949?ContentTypeID=1Mon, 06 Aug 2018 08:05:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:280df0b3-e47a-4295-a9a9-0cf16f95537eMahesh Venkitachalam<p>Do you mean reverse polarity protection? In that case, No. But you can add it it your circuit.
