PMBUS COMMANDS
ThefollowingtableslistsupportedPMBuscommandsand
manufacturerspecificcommands.Acompletedescription
of these commands can be found in the “PMBus Power
System Mgt Protocol Specification – Part II – Revision
1.1”. Users are encouraged to reference this specification.
Exceptions or manufacturer specific implementations
are listed below in Table 2. Floating point values listed
in the “DEFAULT VALUE” column are either Linear 16-bit
Signed (PMBus Section 8.3.1) or Linear_5s_11s (PMBus
Section 7.1) format, whichever is appropriate for the com-
mand. All commands from 0xD0 through 0xFF not listed
in this table are implicitly reserved by the manufacturer.
Users should avoid blind writes within this range of com-
mands to avoid undesired operation of the part. All com-
mands from 0x00 through 0xCF not listed in this table are
implicitlynotsupportedbythemanufacturer.Attemptingto
access non-supported or reserved commands may result
in a CML command fault event. All output voltage settings
and measurements are based on the VOUT_MODE setting
of 0x14. This translates to an exponent of 2–12.
If PMBus commands are received faster than they are be-
ing processed, the part may become too busy to handle
new commands. In these circumstances the part follows
the protocols defined in the PMBus Specification v1.1,
Part II, Section 10.8.7, to communicate that it is busy.
The part includes handshaking features to eliminate busy
errors and simplify error handling software while ensur-
ing robust communication and system behavior. Please
refer to the subsection titled PMBus Communication and
Command Processing in the Applications Information
section for further details.
