Hi all,
I like to drive some switches that half of them have complementary state to other half ( some thing like a full-bridge inverter). in other word if s1=ON, s'1=Off. the situation is like half-bridge operation; so I decide to use a half-bridge MOSFET driver. since charging path of boot-strap capacitor is not secured, I have used two separate DC source to drive FETS. But there is a problem, some times both outputs of driver have same state (both ON or OFF).!!! I am confused what's going wrong in the Circuit. the schematic of the driver is attached bellow. I would be gratefull if you share your comments.
Thank you.
