PPK2 showing crazy current even if it is OFF

[zyghom]

Just see the screen shot - PPK2 is OFF yet it shows 200mA

Hi there,

Can you specify what you mean by the PPK2 is OFF? From the screenshot I can see that you have connected the serial USB cable to the PPK2 and have enabled the power output.

Hi Jared, are you saying 11 Amps is what PPK2 can deliver? and max 22A?

happy new year to you guys

unfortunately it is completely not reliable - please see attached

[Jared]

Hi,

Is this happening with the same frequency as before? Do you see it after restarting the application? 

Do you see it when you lower the supply voltage from the PPK2?

1- frequency: I did not use PPK2 since the last time we spoke - I just opened it today since then

2- when I restart the app all is OK (until next time)

3- I am not sure about voltage: I used today many values between 3.3V and 5V - when it happened I was at max=5V, the current drawn by my project is anything between 30uA and 300mA

Hi,

Ok, thanks for the description. 

And you're still getting this readings if the PPK2 is not connecting to anything else than the Mac?

Please update this case if you have more new observation regarding this issue.

I don't have anything else but Mac

I will keep you posted but as far as I understand there is no specific request from you to me such as log or so? I am happy to help you guys to solve the issue of course as I need a reliable system for my "thingis" ;-)

I meant to say that the PPK2 isn't connected to any device such as the ESP32 that you mentioned earlier? I can tell from the picture you shared last that PPK2 is set to source mode with the power supply enabled. I was wondering if you can disconnect the PPK2 from any DUT and just let it be connected to your Mac and see if the current consumption is still high.

you mean: disconnect the DUC and just let PPK2 run with power turned ON without the load?

[Jared]

Yes, exactly.
