Hello, 

 

The temperature increase is happening before configuration. 

This is abnormal elevated leakage in part of the die. Definitely not dynamic switching power. 

Are you seeing this behavior at only 1 unit? 

 

Next step:

1-can you try power up with slower ramp time? (within timing spec)

2- how many boards manufactured? All showing same behavior?

3- Is it possible to swap unit on the board with another one? - to see if the issue follows unit or follows board

4- Please send snap shot of the device top marking so I can analysia the production test history. 

 

regards,

Farabi

Hello, 

 

I cant do conclusion with behavior description. 

I need to check with production test history. We need the snapshot of the top marking at least 1 or 2 units. 

This is critical for checking the rootcause.

Farabi
