BQ76PL455A-Q1: BQ76PL455A-Q1

Hi All

I am going to use BQ76PL455A-Q1 for communicating 12 boards in daisy chain  in which each board can take 16 cell values. I am also doing cell temperature measurement using the AUX pins given in the IC. Will there be any time delay issues ?? if so can you say approximate values??

    Hello Anson,

    What does "delay" mean?

    Do you mean delay between devices?

    In EC table 6.17 of DS it specifies as TPD-<60ns.

    As for daisy chain, I would suggest to adopt centralized daisy chain, all devices are all in one board,

    because 455's daisy chain is data pass through, not reclocking technology.
