Reduction of current consumption at reset

The reset pin has an internal pull up of around 13kohm, this will draw about 200uA. In addition most internal regulators are powered keeping the chip in reset state, which is another 200uA (if not more). Reset state is not a low power mode, so there is no way to avoid this current consumption.

Hence I would say your measurement of 600uA is with in the expected range, i.e. between 1mA and 400uA.

Current consumption at RESET was 0.6mA.
Is there a register that controls the current consumption at RESET?
How can I reduce current consumption during RESET?

Hi Yokokawa,

can you attach a plot of the measured current consumption of the nRF52832( i.e. EBSHSN module) when a reset is performed?

Best regards
