Other Parts Discussed in Thread: UCD9222
We use the UCD7242+UCD9222 in my board. it works well in the normal temperature. when the temperature below -10℃,
some boards can power up,but,another can no power up. The case is very strange.
Now , we hase two way to fix the program,but we do not understand th reason.
the first way , when we meet the program , we exchange the UCD7242 may fix it.
the second way, when we meet the program , we extend the reset time of the UCD9222 to 1s, In the datasheet, the reset time of the UCD9222 just need 2us.
Can you give some idear the help us to settle the promgram completely.
