How about the recommended max power supplye current？

[OPQ]

Hi,

I didn't found the recommended max power supplye current on the datasheet,could you please help to tell nrf5340 max current consumption and the recommended max power supplye current.

And I look at datasheet the 7.20.15.1 NFCT Electrical Specification,shows that the Maximum input current on NFCT pins is 80mA,is it means my power supply should cover 80mA at least?

Hi,

 

The NFC tag is a passive device. The specifications rates the maximum sink from an external NFC reader.

I didn't found the recommended max power supplye current on the datasheet,could you please help to tell nrf5340 max current consumption and the recommended max power supplye current.

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.

There are some current consumption scenarios defined in the PS: https://infocenter.nordicsemi.com/topic/ps_nrf5340/chapters/current_consumption/doc/current_consumption.html?cp=4_0_0_3_3

 

Kind regards,
