What's the maximum source/sink current of 52832 VDD pins?

Hi, great Nordic teams:

As title, I'm wondering what's the maximum sink/source current of pin  13/48/36 of 52832?

Cause there are GPIO electrical specification about sink/source current but no VDD pins spec in 52832's spec document. 

Are the electrical specification spec of VDD pins and GPIO pins the same ?

See PS 1.4 page 156, figure 24: The current typically levels off around 25mA.

You will have some variance due to production tolerances, so I'd expect the actual short circuit current in the 20-35mA range for a high drive gpio.

Thanks for your great reply! 

But I have another question, could the figure you mentioned represent the current curve of  VDD pins of 52832 (pin 13/48/36)?

Turbo J - that's not the question the OP was asking!

That table just gives the spec of an individual GPIO pin - OP is asking if there's also a separate specification for the supply pins.

In other words, can all the GPIO pins be used at maximum current simultaneously - or will that overload the supply connections?

This is sometimes specified by other chip makers; eg:

Hi Turbo J & awneil: 

Again, thanks for your helping.  

I'd like to know if I could say that the maximum current could go through VDD pins is nearly around 20mA~35mA?

I'd have thought it should be safe to assume that the power pins should be able to support the max current from at least one GPIO - and would hope that it would be more.

Your username suggests that you are with Avnet? If so, do you not have direct access to Nordic support to ask them?
