BQ79616-Q1: Usage of BQ79606 as a bridge with BQ79616

Part Number: BQ79616-Q1
Other Parts Discussed in Thread: BQ79616, BQ79656-Q1, , BQ75614-Q1, BQ79606-Q1

Hello

I would like to know if it is possible to use a BQ79606 as a bridge to a stack of BQ79616 devices, as illustrated in the image:

In case this is possible, I would also like to confirm that this configuration is also possible if I use BQ75614 or BQ79656 instead of BQ79606, since I understand that these devices are pin to pin compatible.

Thanks in advance for your help

    Hi Carlos,

    The BQ79606-Q1 is not compatible to talk to a stack of BQ79616-Q1 devices as a bridge device. The BQ75614-Q1 is also not able to be used as a bridge since it is a non-stackable monitor. However, the BQ79656-Q1 device is able to be configured as a bridge device for the setup you mentioned.

    Best Regards,

    Julia, thank you for your reply.

    Unfortunately I don't think I fully understand, so I send some follow up questions, I hope it is not a problem:

    1) Maybe this first is a dumb question, but just to confirm: Can a BQ79616 be used as a bridge for a stack of the same components BQ79616?

    2) From your answer I understand that the BQ79606 can not be used as a bridge to any of the others monitors. Am I understanding this right?

    3)

    OK, and is it possible the opposite? I mean: use a BQ79616 as a bridge to a stack of BQ79656.

    The reason behind these questions is that I am trying to understand how compatible are these differents ICs in order to select one of them for my design.

    Thanks again for your help!

    Hi Carlos,

    Happy to provide additional clarification!

    1. Yes, the BQ79616-Q1 can be used as a bridge/base for a stack of more BQ79616-Q1 devices.

    2. Yes, your understanding is correct. The BQ79606-Q1 device is not compatible to be used as a bridge for multiple BQ79616-Q1 devices in a stack.

    3. Yes, it should be possible to use a BQ79616-Q1 device as a base/bridge to a stack of BQ79656-Q1 devices.

    Best Regards,

    Julia Louis
