BQ24259: dropped in replacement ?

Part Number: BQ24259
Other Parts Discussed in Thread: BQ24296M, BQ24296

Team,

Since BQ24259 (1A) is not available we are looking for a dropped-in replacement.

Are there any BQ242xx derivatives that can be used as dropped-in replacement?
If not what would be the closest and what HW change would be required?

Would  SW changes be required? Which device will require the less SW changes?

Thanks advance!

A.

    Hi,

    We do not have lower current version of the BQ24259. Referring to 8.3.3.1 Autonomous Charging Cycle on the d/s, the charger device may complete a charging cycle without host involvement with the default charging parameters listed in Table 3.

    Thanks,

    Ning.

    Hi Ning,

    In this case there is a host connected on I2C.

    Can the BQ24296M /BQ24296 replace the BQ24259 (ie just dropped-in place of the BQ24259) and be setup to provide the same charging profile that BQ24259 was using?

    Can the charging profile be re-used or should a new profile be created with the BQ24296M/BQ24296 assuming the same battery model is being used?

    Thanks in advance,

    A.

    Hi,

    The three devices are basically pin-2-pin compatible. The host may customize the charging parameters via I2C. 

    Thanks,

    Ning.
