Actually, turns out there is some contradiction in the LTC4286 datasheet.
It mentions different coefficients in different places. It is all but impossible to
determine if the datasheet is wrong or if the chip uses a variety of coefficients
unless one has a real chip available. Sigh :-(.
We are not the chip vendor, but we could forward your question to vendor.
Could you point out the exact places (which pages) where are the contradiction in LTC4286 datasheet?
See "PMBUS COMMAND SUMMARY", default values:
"IOUT_OC_WARN_LIMIT" says "21.3 mV/RSENSE"
"PIN_OP_WARN_LIMIT" says "2.8/RSENSE"
This seems to contradict "Table 8. PMBus M, B, and R Parameters". But then,
reading it again (and again), I think it is just an odd and confusing way
of trying to describe the 0x7fff default register values. Sorry for the noise.
