mosfet switch problem
Hi everyone,
I want to use some mosfets as switches. I will control them with a microcontroller (3.3V signals).
The problem is that in some mosfets the Source is not connected to ground so I am not sure if the Vgs signal will work.
In my circuit I have two pairs of switches. Mosfets M2,M4 and M1,M3. I want to change the polarity of current by closing each pair seperately.
What do you think of my circuit? Is it ok for M3 and M4 not to be connected to Ground?
Thanks
