BQ40Z50-R1: Change Smbus address

Matthias Rechtien

Part Number: BQ40Z50-R1

Hello,

I want to change the SmBus address without Battery Mangement Studio. I do not understand, how to read / write the address ?

Perhaps somebody can give me a hint / short example ?

Thanks for your help.

Hello Matthias,

There is an example in the TRM, section 13.1.62 0x4000–0x5FFF Data Flash Access()

Just replace the example data flash memory location with the SMBus address data flash location. The location for the address is 0x47D1 (H1 data type) and address check is 0x47D2 (H1 datatype). The address check is just the 2's complement of the address.

Sincerely,

Wyatt Keller
