PMBus_REVISION
The PMBUS_REVISION command indicates the revision of the PMBus to which the device is compliant. The LTC3883
is PMBus Version 1.1 compliant in both Part I and Part II.
This read-only command has one data byte.
CAPABILITY
This command provides a way for a host system to determine some key capabilities of a PMBus device.
The LTC3883 supports packet error checking, 400kHz bus speeds, and ALERT pin.
This read-only command has one data byte.
MFR_DATE
The MFR_DATE command indicates the date of final test of this IC.
The MFR_DATE format is YYMMDD where Y, M and D are integer values from 0 to 9, inclusive using ASCII
characters.
This read-only command is in block format.
MFR_ID
The MFR_ID command indicates the manufacturer ID of the LTC3883 using ASCII characters.
This read-only command is in block format.
MFR_LOCATION
The MFR_LOCATION command indicates the location of final test of this IC using ASCII characters. This field is limited
to a maximum of three characters.
This read-only command is in block format.
