Need a isolated half bridge driver to drive the mosfet CSD19535KCS from TI.
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.?
 

Hi,

i need 100V bootstrap voltage

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.
