Hi Vasileios,

You can find this in the documentation.

Ok Martin. Thank you for your answer. However, can you give a ball-park figure of what it should be when 52840 is powered from its regulators or its DC/DC converters?

Hi Sebastian,

If you measure with a multimeter, why do you have 10Ohm resistor on R90?

I would recommend you to set the multimeter in "ampere-mode" to measure current.

- Check if you have enabled logging. (It should be turned off)

- Set the chip in System Off.

If the current is still high, there is most likely a fault in the way the current is measured.
