https://devzone.nordicsemi.com/f/nordic-q-a/52109/peak-current-ble-and-nfc-durationHi, I&#39;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&#39;t find any timing...

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.</p> <p>Current draw for the transmitter:&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html?cp=3_0_0_5_19_14_1#unique_1123852154">infocenter.nordicsemi.com/.../radio.html</a><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html?cp=3_0_0_5_19_14_1#unique_1123852154"></a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/209564?ContentTypeID=1Fri, 13 Sep 2019 09:05:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b2978461-00fa-4f22-94c8-5e69f0d1c196awneil<p>&#39;fraid not.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/209545?ContentTypeID=1Fri, 13 Sep 2019 08:22:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2f50e27-1c56-45ae-938c-568fcb238e05E.
