Im using this http://rohmfs.rohm.com/en/products/databook/datasheet/discrete/transistor/mosfet/r6010anx.pdf and that last circuit I guess would work but wouldn't the vout be 11.3ish? Since the. 7v drop of the transistor? But now alos what would I do drive it low? A pulldown would waste energy and steal from the gate voltage as well
Turning it on idk if it takes 1ms to fully turn on but turning off id like to make as fast as possible
basically it will be receiving the output from a 5v comparator deciding whether it is on or off, id like to drive the mosfet in one step if possible but with the smallest footprint
