customer put 10K NTC in battery pack and 250K NTC to ground , they found it will shutdown in -10℃,they need BQ24092 can shutdown at 0 ℃, Please help check if the set is right .Thanks .
Can you tell us what type of NTC the customer is using? We use the SEMITEC 103AT-2 or Mitsubishi TH05-3H103F for our calculations.
Thank you for that information, this ntc meets the same B value that we expect. You didn't include the information for the 250K NTC though. In the standard profile you would have a 0C - 60C operation but you are saying the customer is seeing a -10C - 45 C operation correct? Can you share what 250K NTC they are using?
