Hi,
I have a question about Fuel Gauge device.
I will change Fuel Gauge device which is embedded in product from BQ30z554-R1 to BQ20z45-R1.
I know that communication interface of those device is SMBus.
Is there any difference between BQ30z554-R1 and BQ20z45-R1?
For example, Slave address, Master address, register value and so on..
Do I have to modify source code when I change fuel gauge device from BQ30z554-R1 to BQ20z45-R1?
Is there anything to modify about battery management source code?
I want to know Fuel Gauging algorithm of both Fuel Gauge IC is same or different.
I read Document about both FG IC, In BQ30Z554 Document, there were SLUA364B report and
In BQ20Z45 Document, there were SLUA364 report.
I clicked SLUA364B and SLUA364, both two report were same.
Both FG IC are made from TI and communicate by SMBus, so I guess there is no difference.
Please help me out.
Thank you. :)
