PPK2 handling of in-rush currents?

[Pema]

Hi,

I have a card with some large capacitors in parallel with the VBAT line. How does the PPK2 work (in source mode) at board start-up where there might be a short in-rush current that might exceed the rated 1A? Does it limit the output current to 1A or will the PPK2 break down?

Is there a difference if I use the PPK2 amp meter mode together with an external supply (battery or supply generator) with regards to board start in-rush current that might go above 1A? Will it manage or break?

Regards,
Peter

The kit will manage fine at least up to 2-3 A inrush current. The current reading will of course be saturated above 1 A. 

In SMU mode, the regulator will limit the current to 1.2 A.

You do better than ST's X-NUCLEO-LPM01A energy monitor, then!  

That will just abort the acquisition, and crash the GUI on overcurrent.

Ok, thanks.
