Problems with BQ27531

Hi

I'm having some problems with inconsistency between the manual & EVM for the BQ27531.

I have the September 2013 version of SLUUA96 and version 0.9.91 of bqEVSW.

A quick search of the forum threads hasn't shown any hits and I was wondering if anyone else has these problems, do I have the wrong version of something or is there an error somewhere?

1) The charger product number reports as "40" and reg A reports "0"

    The TRM (page 29) suggests that the bq24192 should read as "010" which is "2"

    When I read the register on our own board I get "4" which is about right for the bq24190 we fit.

2) The CC Offset described on page 41 of the TRM appears to be "-0.72mA" on the EVM but is a signed integer with a default value of -1200mA in the TRM.

3) The Board Offset reads as “-0.09uA” on the EVM but should be a signed 8 bit integer of default value 0 according to the TRM.

4) Several of the Temp model coefficients are floating point numbers on the EVM but are integers in the TRM.


Cheers
