This is probably a stupid question but I have been searching everywhere and cannot find a solution that works.
I am trying to come up with a circuit using transistors that acts as a SPDT switch to toggle from being powered by one supply to another. The switch enable signal is being supplied by a Raspberry Pi which has very limited current capability (16mA max) so FETs are preferred over BJTs. The device being powered draws around 100mA.
Here is what I am going for:
I have pondered using relays, but I am going for as small of a footprint as possible and relays are rather large (and expensive, especially if using SS relays).
My original intent was actually to use a quad bilateral switch (CD4016BE) but the current capacity just isn't there.
EDIT: I think this is the route I'm going to take.
(with BS170 as NMOS device and IPP45P034L11AKSA1 as PMOS device)
Thanks for all of the help.
