Hbridge driver

Hi,
I need help to drive this hbridge https://www.semikron.com/internet/gecont/pdf/1654.pdf

The power supply is 4 lead acid batteries connected in series (12V/42Ah). I am also using microcontroller 18F4480 https://www.farnell.com/datasheets/61838.pdf

Why start a new thread?

Copied any pasted from the reply I made to the other thread:

For minimum voltage loss the MOSFETs need a gate voltage of 10V to turn on fully.

Unfortunately the high side MOSFET gates need to be 10V above the positive supply to turn on fully so you either need a +58V rail or bootstrapping capacitors which only work at AC.

sorry bout that..i thought i had posted in teh wrong forum..btw i'll stick to teh old thread https://www.electro-tech-online.com/threads/eectric-go-kart.88235/.
