Dear all,
I am testing a setup of bq20z45-R1 controlling the bq24707A - or the bq24725A charger which is meant to be a design where the gas gauge module are controlling the charger without a host.
I have one question: After I change some of the DF - parametre which will affect the charger (changing current, battery status alarms etc) how often does the gas gauge transmit the data to the charger on the SMBus ? Is it something I can Control or is it a part of the firmware ? Would theer be any difference between the bq20z75, the bq20z45 and the bq40z50 regarding thsi timing ?
Since I have just started the testing and have little experience I would appreciate some comments from those who might know the answers.
The way of combining the gas gauge and the charger forming a smart battery looks very promising.
Best regards
Kjell
