BQ40Z80: multiple BQ40Z80 via single interface

Part Number: BQ40Z80

Dear team,

We have some application issues that want to refer to your comments here.

Q1: SMBUS interface

There is 4pcs BQ40Z80 for four indiviual cell pack used in one system, and communicated by one MCU; but there is only one avaible remaining SMBUS interface resource in the host MCU.

Could you give some comments on that how to achieve every indivivual BQ40Z80 control? should I change the every single BQ40Z80 SMBUS address seperately will be fine? Any other process should I do in the host MCU side?

Q2: Data flash values - setting

How could I write serveral continuous configuration setting from one specific address? For example, write three setting from address 0x4c90. If there is a standard format requirement here?

Thanks

Best regards

Mia Ma
