The nRF52832 spec. document specifies that the current consumed in System OFF / No RAM retention / Wake on LPCOMP mode is 1.9uA. However, if I measure the current using the Nordic PPK, it is only ~0.4uA. I assume my software / SoC works correctly because I can see that the chip goes in to the system off mode and wakes up by LPCOMP interrupts.
Could anyone confirm if 1.9uA shown in the spec is a correct value? Do you have any idea why the actual measured current is much lower than the spec.?
I have a feeling that the 1.9uA in the PS is wrong. I'm pretty sure that 0.4uA is correct. I will try and measure it here.
Stian, thanks for the quick response. Look forward to hearing the result from you.
