PMBus Power-Supply Data Logger
READ_POUT (96h)
The READ_POUT command returns the latest calculated power-measurement value for ADC0/1 and ADC2/3 voltage/
current-coupled measurements as shown in Table 15 . The 2 data bytes are in DIRECT format. When the ENABLE pin is
low, this command returns 0000h when read.

DESCRIPTION
READ_POUT = READ_VOUT x READ_IOUT
READ_POUT = READ_VOUT x READ_IOUT
PMBUS_REVISION (98h)
The PMBUS_REVISION command returns the revision of the PMBus specification to which the device is compliant. The
command has 1 data byte. Bits [7:4] indicate the revision of PMBus specification Part I to which the device is compli-
ant. Bits [3:0] indicate the revision of PMBus specification Part II to which the device is compliant. This command is
read-only. The PMBUS_REVISION value returned is always 11h, which indicates that the device is compliant with Part I
Rev 1.1 and Part II Rev 1.1.
MFR_ID (99h)
The MFR_ID command returns the text (ISO/IEC 8859-1) character of the manufacturer’s (Maxim) identification. The
default MFR_ID value is 4Dh (M). This command is read-only.
MFR_MODEL (9Ah)
The MFR_MODEL command returns the text (ISO/IEC 8859-1) character of the MAX34446 model number. The default
MFR_MODEL value is 54h (T). This command is read-only.
MFR_REVISION (9Bh)
The MFR_REVISION command returns two text (ISO/IEC 8859-1) characters that contain the device revision numbers
for hardware (upper byte) and firmware (lower byte). This command is read-only.
MFR_LOCATION (9Ch)
The MFR_LOCATION command loads the device with text (ISO/IEC 8859-1) characters that identify the facility that
manufactures the power supply. The maximum number of characters is 8. This data is written to internal flash using the
STORE_DEFAULT_ALL command. The factory default text string value is 10101010.
MFR_DATE (9Dh)
The MFR_DATE command loads the device with text (ISO/IEC 8859-1) characters that identify the date of manu-
facture of the power supply. The maximum number of characters is 8. This data is written to internal flash using the
STORE_DEFAULT_ALL command. The factory default text string value is 10101010.
MFR_SERIAL (9Eh)
The MFR_SERIAL command loads the device with text (ISO/IEC 8859-1) characters that uniquely identify the device.
The maximum number of characters is 8. This data is written to internal flash using the STORE_DEFAULT_ALL com-
mand. The factory default text string value is 10101010. The upper 4 bytes of MFR_SERIAL are used to unlock a device
that has been password protected. The lower 4 bytes of MFR_SERIAL are not used to unlock a device and they can
be set to any value.
