BQ25713: migration from BQ25703A --> any recommendations ?

Pial

Part Number: BQ25713
Other Parts Discussed in Thread: BQ25703A, BQ25723

Dear team,

I am reaching out to you to check if we had any recommendations for migrating from BQ25703A to BQ25713 (sourcing reasons).

Datasheet states that these devices are pin to pin and software compatible, but I am sure a few differences needs to be looked at/evaluated, before simply changing the part number on the board.

Many thanks in advance for your support!

Best regards,

Why not migrate to BQ25723?

Hello,

Thank you for your support.

The idea is to have as little change as possible between BQ25703A and a newer device.

I did not check all the specifics, but I believe 723 is featuring a different current shunt value ?

The question here is to know if there is any hardware or software change to be considered when using BQ25713 (or another if more relevant) instead of BQ25703A.

Can you let me know ?

Thanks again!

Best regards,
