https://devzone.nordicsemi.com/f/nordic-q-a/96787/how-about-the-recommended-max-power-supplye-currentHi, I didn&#39;t found the recommended max power supplye current on the datasheet,could you please help to tell nrf5340 max current consumption and t he recommended max power supplye current. And I look at datasheet the 7.20.15.1 NFCT Electrical Specificationen-USTelligent Community 13Fri, 17 Feb 2023 13:13:06 GMThttps://devzone.nordicsemi.com/thread/410654?ContentTypeID=1Fri, 17 Feb 2023 13:13:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:178e3b43-1ddd-48e4-a6cf-0de564b1a682H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>The NFC tag is a passive device. The specifications rates the maximum sink from an external NFC reader.</p> [quote user=""]I didn&#39;t found the&nbsp;recommended max power supplye current on the datasheet,could you please help to tell&nbsp;nrf5340 max current consumption and t<span>he&nbsp;recommended max power supplye current.</span>[/quote] <p>The maximum current the chip can deliver is highly based on your hardware configuration (ie. DCDC used or not) and how your application works. I would recommend that you power profile your application to see the peaks.</p> <p>There are some current consumption scenarios defined in the PS:&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/chapters/current_consumption/doc/current_consumption.html?cp=4_0_0_3_3">https://infocenter.nordicsemi.com/topic/ps_nrf5340/chapters/current_consumption/doc/current_consumption.html?cp=4_0_0_3_3</a></p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
