I'm working on an H-Bridge to control a drill motor that requires 18V and 50A of power. I found and example of an H-Bridge at http://www.hvlabs.com/hbridge.html . I have studied the schematic, and from my knowledge it should work, but I would like to get a 2nd opinion on it before I buy the parts.The schematic can be found at http://www.hvlabs.com/Images/dcmotorcontroller.jpg and more info on the HIP4081 can be found at http://www.hvlabs.com/files/HIP4081.pdf . I
That's 50A of current.
Typical implementation using that HIP4081 IC.
Ever made or done anything like this before?
