Hippy,We do really need some clarity on what the power circuitry is on the Pi 5.If I recall correctly, over voltage protection exists only for protecting power being applied to the usb-c power port, not the pins in the IO header.
If you apply more voltage than you're supposed to via the io header power pins, you're going to damage the pi.
In the Good Old Days every +5V was connected together; albeit with diodes, fuses, high-side drivers in the path. These days it's all a lot more complicated and not publicly documented at all for the Pi 5.
If powering a PI 5 with 5V via USB-C is different to powering via the 40-way header, that suggest they must be using different power paths. But how does powering via the header and delivering 5V out on USB-C to cater for USB OTG work ?I have always maintained that it doesn't matter why someone wants to know, it's good enough that they want to know and they shouldn't be required to justify themselves.Why bother with this anyway?
Why they want to know doesn't change the answer when it comes to electrical specifications and characteristics.
Knowing why they need to know, or use case, is the difference between a "don't worry about it, you're good" answer and "Yup, you need to worry about it, here are a few different ways to deal with it."
That was the reason of my question, not that they should care about it.
