Re: [CAD_CAM_EDM_DRO] HIP4081 was Re:Re:Black box/kerr

Hello,

No I did not do anything special, I lost lots of mosfets to find out that
I can get no where near the promised upper limit of 80 volts. As long as I
stay down at 30 volts all is cool. If I had it to do over again I would
never use this chip again. I am building a spindle drive, 100 volts 15 amps,
that will be under pic servo control, but it will use the ir2104. So far I
have not had any problems in my limited testing.


I admit it was a bad choice, and one I would love to change, but as long
as I stick with my 24 volt servos I will continue to use the drives.
