Part Number: BQ40Z50
Other Parts Discussed in Thread: BQ24725

Dear Expert :

                     If my solution is bq24725+bq40z50

                     Generally bq24725 is matser, bq40z50 is slave.

                     If I change bq40z50 dataflash setting to master mode. be24725 as slave.

                     Does it meet Level 2 smart battery charger

  • Hi Dustin,
    Setting the [BCAST] bit in bq40z50 will enable the broadcast of the charging voltage and current to the bq24725 for meeting the level 2 charging requirements.
    It is important to note that apart from broadcasting the charging voltage and current and any alarms, the bq40z50 is not considered a SMBus host.
