Part Number:TPS3851
Dears:
We use TPS3851G25EDRBR in our Board, and the bord work well in normal temperature.
These days we made some boards working under 50℃~70℃ temperature, and we found an issue about it.
Sometimes RESET pin or WDO pin of TPS3851G25EDRBR will be low level for a long time, then we tested the watching Power's and MR's Voltage they are all high level.
Why it happend?
Pls. kindly help to give some advice, thanks a lot!
