So I am using the following circuit to switch between VIN 0-30v and USBVIN 5v.
I thought I found the ideal solution until I realised the FET in the schematic only has a max VGS of 8V. But I don't fully understand how the max ratings work in a situation like this because when VIN is supplied both the Source and the Gate will be the same voltage.
Also the Vds is only 20v as above the Fet isn't being used in a normal application so I'm not sure if this will cause a problem?
So my question is will the circuit be ok along with the FDN340P or do I need to swap it out with a FET with a max VGS and VDS of at least 30v?
