Other Parts Discussed in Thread: BQ27510-G2, BQ27510-G3, BQ27520-G4

Hi all

We are using BQ27510-G2 in our existing product. I already taken Calibration for 20 Boards using BQ27510-G2 and generated Golden File.

Now we are changing to BQ27510-G3 for that we are going generate new Golden Image for BQ27510-G3.

For that I like to know the following

For generating new Golden File can I use the average Calibration data colleacted using BQ27510-G2 or we need to take new Calibration for 20 Boards Using  BQ27510-G3.

I need to now the difference between BQ27510-G2 and BQ27510-G3.

Where can I get the TRM for BQ27510-G3.

Error in opening "http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=sluua97&fileType=pdf" got from BQ27510-G3 Data Sheet.

Thanks

Pushpanathan

    If you're only doing a firmware upgrade from -G2 to -G3, you should be able to keep the same calibration values.

    The bq27510-G3 TRM hasn't been released for a while, but the bq27520-G4' s TRM (SLUUA35) can be used as it's very similar to the bq27510-G3. SLUA658 is the change list for the bq27520-G3 to -G4 and is also applicable to the bq27510-G3.
