Motor driver IR2130

Hi everybody

I am new in the forum and I would like to hear from you about the IR2130. Has anyone used it? I have had many troubles with this driver, even though I have used before.

My application is the control of a 3-phase PMSM motor. The system was working quite OK until a couple of days ago, when the IR2130 started to burn for no reason. I had a LC filter connected after the IGBT bridge and I though it could had been the problem. Then I REPLACEed series resistor, but it did not help.

Now the driver is burning just by turning on the motor power (the machine does not starts). And I have checked all the contacts many times.

If anyone has had any (good or bad) experience with this IC, it would be very nice to get some help!
Thank you in advance.

Regards

Goncalves
