I'm designing a new motor driver for a DC motor which has starting peak current of 30A and 28Volts power supply. Previous engineer used an integrated motor driver IC solution (VNH3SP30-E) that has a MOSFET (Full H-bridge) inside an IC. There are so many customer complaints that it is blowing up in the field. When I look at the IC there is not good separation and everything things runs off the high power line. I dont know what is the advantage of using a integrated driver solution over original MOSFET/IGBT approach. I personally think having external FETs would be a safer approach. Has any one used the integrated solutions before ? if yes, is it better than original power electronics. I'm trying to see which is a better approach.
