This is my first post (been an avid user though as I usually find an answer to my questions... this time I cannot despite a few days of searching.
I've created a push pull gate drive circuit for a high side back to back mosfet circuit... and I have it working in circuitlab and prototype...
However, I would like to know how to create it so that the pull down part of the totempole only pulls the gate down to VCC - 6V... to allow driving of voltages much higher than max Vgs (which for my circuit is -/+20V).
I've got a transient diode in there at 18V.. but that will not work for sustained VCC > 20V. I've tried various configurations of different circuits but can't get anything to work!
any pointers much appreciated.
