Hi sir, 

My name is Vishaal and i am currently an B.Tech. Undergraduate. we have implemented the hardware model of  TIDA-00443 and currently in testing part. we have an issue while testing the hardware where after giving an supply of 150V till that my Gate driver UCC27517ADBV  is generating pulse where after 170V my gate driver gets short (VCC and GND gets shorted) and damaged. I have tried for almost 3 times but i could not able to find the issue and also my Schematic is as per the reference. Can you help me to figure out this issue as soon as possible please.
