I had selected lm5106 as the gate driver earlier as i need 100V bootstrap voltage but it would be better if i get an isolated driver.?

Bootstrap voltage usually is about 12V. But when bridge output is HIGH, then this voltgae is shifted up on bridge_voltage. *** Usually the isolation is on the input side of the gate driver, so it has nothing to to with botstrap circuit... A schematic could help. Klaus
