Other Parts Discussed in Thread: ADS7830
Tool/software:
Hello,
I am trying to convert data read from a TPS53647 to decimal format.
I am using your tool "SLINEAR11 FORMAT.xlsx"
Some data are "good" but other are "WRONG" example:
READ_VIN register 0x88:
Read value: 0xD2FD, with the file SLINEAR11 FORMAT.xlsx we have a decimal value of 11.953125 V this value seems to be good an ADS7830 device read 11.84V for this rail.
READ_VOUT register 0.8B
READ value: 0x007C, with the file SLINEAR11 FORMAT.xlsx we have a decimal value of 124 V !!!, this value is WRONG ! the output voltage of the TPS53647 con not be 124V !
For this rail the ADS7830 read 0.879V, this value is very closed to the value measured with a multimeter.
Where is the problem ?
The value read in the register 0x8B ?
In this case why the reading of fixed value are good ?
Reading PMBUS_REVISION (0x98) return 0x11, reading MFR_ID (0x99) return 0x5411, reading MFR_MODEL (0x9A) return 0x4701
The formula in the Excel file ?
Thank you for your help,
Best Regards,
Thierry.
