Dearall,
For aLiFePO4application, high current pulse loading and lowaveragepower consumption between pulses, we are now using bq20x75V.160/1.80 with good results. For a new development of a similarapplication we planned to usebq20z45-R1due toimprovedITAlgorithm andJEITAspec compared to bq20z75..
We haveno experiencewiththe new versionbq40z50- so my questions are:
- Will the bq40z50 represent so many improvements compared to bq20z45 that we should go for that new version instead ?
- I have noticed a post at the forum regarding the use of bq20z50 in a battery backup application and also the article written by Keith James Keller regarding Improved LiFePO4 cell balancing for bq20z45. Even thoug we have a different application would it be a better alternative to replace the bq20z75 with bq40z50 because of the LiFePO4 flat discharge voltage curve ?
Best regards
Kjell
