PMBus 5-Channel Power-Supply Manager
and Intelligent Fan Controller
READ_FAN_SPEED_1 (90h)
The READ_FAN_SPEED_1 command returns the fan speed in RPM. READ_FAN_SPEED_1 is updated once a second,
even if the fan is disabled. The PULSE bits in FAN_CONFIG_1_2 must be properly configured to receive the correct
fan speed. Fan speeds below 60 RPM (360 RPM for dual mode fans) are reported as 0 RPM. The 2 data bytes are in
DIRECT format.
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 it 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 device model number. The default
MFR_MODEL value is 52h (R). 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). The default MFR_REVISION value is 3031h (01). 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 3130313031303130h.
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 3130313031303130h.
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 3130313031303130h.
