Other Parts Discussed in Thread: BQ24210, BQ25170, BQ25171-Q1
Hi,
I found two quite similar chargers, but both have a different recommend operating temperature:
BQ24010: -40C to +125C
BQ24210: 0C to 125C
Because I require charging below -30C, I thought I needed to change the charger I already have (BQ24210) with the BQ24010. However, I got confused while looking in further detail at the datasheet. All the electrical characteristics for both chargers are valid over a temperature range of 0°C ≤ TJ ≤ 125°C.
What is the difference between the two provided the EC of both are only valid between 0°C ≤ TJ ≤ 125°C? Are both chargers okay to use below 0C?
The question is not really about whether the chargers will survive, it's more about whether I can trust their operation in terms of EC and it's tolerances at temperature below 0C. We don't want to risk getting a batch that suddenly has different ECs and therefore makes our device fail the requirements as a whole.
Kind regards,
Martin
