power profiler v4.2.0+ output voltage

Dear,

We were testing our products for low battery tests, and we found a bug in the firmware versions of v4.2.0+ and higher.

The power profiler sends out the wrong voltage, from what was said.
The PP kit II gave lower voltages than set was, this happened when we lowered the voltage in steps of 100 mV from 3.3 till 3.1.
We saw the Power Profiler gave the correct voltage at 3.3v and higher, but gave arpund 300mV to less/little voltage at the 3.2v and the 3.1v ranges.
We added an electric scope to see the set voltages, and we noticed a drop.

We rolled back previous version of the PP and from v4.1.3 and lower and these work fine, the correct voltages were given.
We think it's a firmware bugg, because rolling back a previous versions of the firmare fixed the problem, we haven't seen before.


Greeings,

  • Hi Angus,

    Thank you for reporting this issue.

    We have checked this, and it seems that there is a bug related to the calibration. We will look into this issue further.
