However I'm not using the enable pins, and there is also the second reverse polarity protection mosfet which blocks the discharge path, so should be fine. Only thing is that it also has an internal 200Ω discharge path which is activated when the enable signal is low - which would give unexpected results since there is no direct ground connection, only the resistor. It's even specifically made for slight delay + slowed turn on (exactly what I need). Max current useage seems to be in the microamps range per datasheet, so the zener divider thing should work with that. according to the datasheet the IC raises the gate voltage to 11.5v above the source, so even with the 'floating ground' hack, it won't see a source voltage above it's 20v max rating. Using a zener diode + resistor divider to generate a 'floating ground' (is that the correct term?).
It's only rated for 20v source voltage max, so I came up with this solution to float it on the high side: I think I have a solution that should work, using SLG55021 gate driver.
