PFET power switch review
« on: July 10, 2024, 05:03:44 pm »
Hi,

Can you take a look and provide a review of this power circuit please?
The button is a latching push button.

The input can range between 6 and 20V. This is because the power could be 20V (USB C) or down to 6V (2 Li cells in series)

You are running SI7155 right at its absolute maximum gate voltage of 20V. Usually TVS would be closer to the fuse. Other than that it seems ok.
Don't know if R1/C5 will really do anything.
