Hi, I'm looking for information about duration of peak current on BLE and NFC mode on nRF52840.
Do someone have any answers ?
I saw that peak current on NFC is 80mA max and until 4.6mA on Tx mode but I can't find any timing...
80 mA for the NFC is max current into the pins, from the antenna. The current draw when the NFC is active is around 4 mA, mainly due to CPU activity. You should use the wake up on field to keep the current draw down.
