Ultra Low Power on B523

Hello @thrmttnw

I had a similar problem when I also tested the eval board with a PowerProfiler Kit 2, have a look at my thread here:

[B523][DeviceOS 3.0.0] High current consumption during sleep

Short update - I have an almost identical E-Series based board with same onboard peripherals as the B5-SoM board. However, I am successful in setting the sleep modes on that board (both ULTRA_LOW_POWER and HIBERNATE). [deep-sleep-hibernate] In addition, setting the B-Series board to HIBERNATE gets the consumption down to 4,63 mA from ULTRA_LOW_POWER’s 4,97 mA. If I placed the B523 in the eval board and run the following: // Initialize Power Configuration SystemSleepConfiguration meas…

It was primarily the Ethernet component that has a high power consumption during my testing, after desoldering It lowered the power consumption a lot, then you still have the PMIC and fuel gauge using power typically.
