Thanks a lot for the replies, but still my original question seems to be unanswered.
- mosfet switching on and off as the arduino or is inverted.
- is this circuit correct or any modifications are required.
- explaination to the working of the bootstrap circuit for mosfet driving
herbschwarz:
First, this is not a half-bridge circuit: it is a high side driver.
This is not my design or the wordings, i have taken it from another discussion on this forum and have attached the link to the original thread also.
