BQ78350 Missing registers description

Fred P
Expert 2235 points

I can't find any reference to the usage of "FET Off Time" and "Delay" registers in "Ship" subclass although it looks related to the Shutdown Mode configuration (section 7.4)...
Moreover, "Delay" register maximum and default values in section 7.4 do not match with 18.1 table.

Regards,

Fred

     For the "Ship" subclass, after receiving shutdown command, all FETs are turned off after "FET off time" is passed and shutdown the gauge after "Delay" time is passed.  The other shutdown time parameters are related to the voltage based shutdown.

    There are mismatches and typos in the document which are being addressed in a document update.  The gauge shows the proper defaults.  Thank you for pointing this one out.
