Hello-

We have been seeing failures which we believe to be caused by the TI cell monitoring BQ76PL536PAPR. When our products are on the shelf we are having a communication fault.  We read on TI’s website that the BQ76PL536APAPR (rev.A) has improved communication, and was wondering if the older rev had a known communication issue? Specifically:

BQ76PL536PAPR

  1. What were the faults with the initial rev of the chip?
  2. Is there a way to identify chips with faults?
  3. Is there a way to induce the failure in the part (for internal testing) ?
  4. Would it be possible to send back what we believe to be failed components for analysis?

BQ76PL536APAPR

  1. What improved in the new re of the part?
  2. List of potential changes with the new component?
  3. Can we get a copy of any information that is available (data sheets, quality documentation) 

Thanks and Best Regards
