I have a board we've been building for a few years with no problems. This last build we are getting a large percentage of ADM3251E that are getting hot and failing. Upon power up they are consuming a larger current that a good IC. One of the devices actually set of a mini fireworks display blowing a hole in the package (see attached).
The date codes we are experiencing this problem is 1718, 1725 and 1732.
Is there a reason why this sudden change has occurred?
