Bootstrapping a bidirectional MOSFET switch?
"Or can I just stick 10V in it like shown?"

"Yes: however, your driver must be isolated as the gate nodes need to be Vgs(on) above the common source node. Photovoltaic isolator ICs or driver-transformer-rectifier combinations are usually used for this task -- either way, it's a switchable, isolated, low-current 10V gate supply. You'll want to work out how much current the isolated gate supply must pull, though (Qg is your friend here), so that you can determine if a PVI IC will suffice, or if the more-parts approach (transformer driver IC, small transformer, and rectifier) is needed."

There you go, if you stumble upon this.
