BQ20Z655-R1: Similar new device with exactly the same host communication

Part Number: BQ20Z655-R1
Other Parts Discussed in Thread: BQ40Z50-R2

Hi team,

A customer is looking for BQ20Z655 / BQ20Z655-R1 in their design to make sure they are using the newest device and minimizing the risk of having to replace it in the next 10 years. Is there a similar new device that communicates with a host in exactly the same way (same registers etc.)?

The PCB of the battery is going to get adjusted but the software of the separate host product will not be updated. This is to ensure battery downward compatibility to old hosts without update capability in the field.

Thank you,

Franz

    Hi Franz,

    We don't have a new device that has exactly the same registers. We will continue to manufacture BQ20z655-R1, customer can continue using it! When the customer decides to update their design, we highly recommend migrating to BQ40z50-R2 because this gauge has the latest HW and FW. 

    Regards,
