【nRF52832】When use 1.8v power supply，power consumption reach to 14mA current.

dears ,

Attached is our design. when using 1.8V power supply.by default ,current is 14mA.

Would you please help to  check it? Thanks a lot.

Thanks for your supporting.

It is average current. method is adding current meter to supply circuit.protocol stack is S132 7.0.1. 

[FrankBi]

Is there any suggestion for this case? Thanks a lot.

For average current 14mA sounds a bit high. Are you using any other peripherals in your design using the same supply circuit?

A couple more of suggestions:

What kind of software or software example from the nRF5 SDK are you running on the chip?

And can you test using this file and measure the current consumption then?
system_on_sleep_nrf52832.hex

You also need to check if you multimeter/current meter has the capacity to measure the average current accurately, we recommend using the PPK2 for measuring power consumption on our chips:

Dears,

Thanks for kindly support.

After using your image, we found it should HW issue. About that, is there any suggestion?

Thanks.

Hi,

Depends. What were your measurements when you tested system_on_sleep_nrf52832.hex? Are you suspecting any particular HW issue? Why are you suspecting that? Have you tried to test system_on_sleep_nrf52832.hex on multiple boards or just the one? Are the measurements the same?

BR,
