Good to know that it also should work with lower voltages.
I remember using the SiSB46DN too. I switched to a MOSFET with SOIC-8
package because for me it's easier to solder. But I paid too little
attention to the Vgs(th) value.

Oh nice, I've been using the same chip but I wanted to double check if
there wasn't some other solution people were using.
I went with the SiSB46DN suggested by the datasheet and I've been fine with
protection even for 3.3V with a lower voltage bound of 3V.
I've also tested a circuit for
Looks really nice

Maybe 5V is not enough to fully turn-on the mosfet, I have to check that...

What is your method of input protection?

Nice work!

I've had some of the 'purple' boards from JLCPCB - all good - especially
delivery to UK.

The boards are from China, good quality, fast delivery and good prices. I
tried to order in Europe, unfortunately as a hobbyist I cannot afford their
prices.

OSH Park ? They do excellent work (love that ENIG finish...) but I only
use them for very small boards (less than 3 square inches). Even though
they are just across town from me, it's faster and cheaper for me to have
larger boards fabbed in China (send out Thursday nite, boards delivered on
