I'm using the LM5106 to drive half bridge from some PWM all the way to DC. If you're curious about the application, this is for high voltage logic of secret pattern/type, and of course it needs feedback to verify what is being sent.
My concern is that at DC, the bootstrap capacitor and gate charge will leak down after a few seconds and will shut off. So I added a 100k resistor to trickle charge the bootstrap capacitor at ~90uA so it can stay charged at DC. I've never seen it done like this, so I am here to ask if anyone else has and maybe this is a bad idea.
In my schematic, there is a 9 isolated supply between Veh+ and Hi Drv.
Will this work to keep the high side gate 'on' for some arbitrarily long time, like 10 hours?
