I'd really like to see how you can switch an n-channel MOSFET in a
high-side configuration with a 12V load having only a 12V supply and a
TC4426 and nothing else... =


How do you do this? Can you draw a schematic? Where does the 12V Vgs come
from (which needs to be 12V above the MOSFET's source, which may be
anywhere between 0V and 12V and high-Z)?

Thanks,
Gerhard
