UCD90320: UCD 32-Rail Device – Page Number Mapping for AMON10 onwards and temperature reading processor from host pmbus

Part Number: UCD90320

Hi TI Team,

I'm using a 32-rail UCD device and have connected PTAT temperature on a temperature sensor output to several AMON inputs (specifically AMON10, AMON11, AMON16, and AMON24). These voltages are being read via PMBus using an external master.

The application note above provides a table showing the relationship between Page numbers and Output Rails, but it only lists mappings up to a certain point (e.g., Page 0 → Rail 1, Page 1 → Rail 2, etc.). However, it does not clearly indicate the Page numbers for Output Rails beyond Rail 4.

Could you please clarify:

  • What are the Page numbers corresponding to AMON10, AMON11, AMON16, and AMON24?
  • Is there a complete mapping table available for all 32 output rails and their associated page numbers?

  • What process should i follow to read the AMON10,AMON11 temperature hex value?

Thanks,
Sunil
