Part Number: BQ40Z50
Other Parts Discussed in Thread: BQ24725

Hi Team,

I know BQ40Z50 supports SMBus braodcast function. May I know what are the address for the following:

1. ChargeCurrent()

2. ChargeVoltage()

Can BQ40z50 communicate with BQ24725 directly through SMBus? Thanks.

Best regards,

Andy Chu

    1. Charging current can be read off of 0x14 and voltage off of 0x15. The gauge can broadcast chg current and voltage. To know if the charger can communicate with the gauge, please post the question in the charger forum. It will be answered by charger apps.
