MFR_COMPARE_USER_ALL

The MFR_COMPARE_USER_ALL command instructs the LTC3888-1 to compare current operating memory with the

contents of the internal EEPROM. If the compared memories differ, a CML fault is generated.

This write-only command has no data bytes.

MFR_FAULT_LOG_STORE

The MFR_FAULT_LOG_STORE command forces a data log to be written to RAM (at any temperature) and transferred to

internal EEPROM as if a fault event had occurrred. Execution of this command will lock the fault log until a subsequent

MFR_FAULT_LOG_CLEAR is received. Die temperature limitations apply to the EEPROM write, as noted above. This

command will generate a CML fault if the Enable Fault Logging bit is clear in MFR_CONFIG_ALL.

This write-only command has no data bytes.

MFR_EE_xxxx

The MFR_EE_xxxx commands facilitate bulk programming of the LTC3888-1 internal EEPROM. Contact the factory for details.

USER_DATA_0x

The USER_DATA_0x commands provide uncommitted EEPROM locations that may be applied as system scratchpad

space. USER_DATA_00 and USER_DATA_01 should not be modified when using the LTpowerPlay GUI. Some contract

manufacturers also reserve use of USER_DATA_02 for their own inventory control.

PMBus COMMAND DETAILS (EEPROM User Access/Unit Identification)

The following three read-only commands use block format.

MFR_ID

The MFR_ID command returns the manufacturer ID of the LTC3888-1 using 8-bit ASCII characters.

IC_DEVICE_ID

The IC_DEVICE_ID command returns the ADI IC part number using 8-bit ASCII characters.

MFR_SPECIAL_ID

The MFR_SPECIAL_ID command returns a unique binary product code for the device. X is adjustable by the maufacturer.

This read-only command has two data bytes.
