【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.

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,

Marjeris

Dears,

Because we use system_on_sleep_nrf52832.hex ,this image could get almost the same result.

about 14mA current.so we guest HW issue.also,this new design HW changed, bring a LDO ,power to sensor.

thanks.

Do you have many sensors and other devices that also draw current on your PCB? Perhaps it's not only the nRF chip drawing current. If you want your whole schematic reviewed you can create a private ticket and share your files with us.

OK,got it. I will do it.thanks Msromero.
