STATUS_BYTE
The STATUS_BYTE command returns one byte of information with a summary of the most critical faults. This is the
lower byte of the status word.
The following status bits can be cleared by writing a 1 to their position in the STATUS_BYTE command:
[7] BUSY
This permits the user to clear status by means other than using the CLEAR_FAULTS command. These are also the only
bits of this command that can initiate an ALERT event.
Bit 6 of this command will be set whenever the channel is turned off. Setting this bit does not assert ALERT.
This command has one data byte.
STATUS_WORD
The STATUS_WORD command returns two bytes of information with a summary of the unit’s fault condition.
The following status bits can be cleared by writing a 1 to their position in the STATUS_WORD command:
[8] UNKNOWN
[7] BUSY
This permits the user to clear status by means other than using the CLEAR_FAULTS command. These are also the only
bits of this command that can initiate an ALERT event.
Bit 6 of this command will be set whenever the channel is turned off.
Bit 11 of this command will be set whenever the channel output voltage is below the POWER_GOOD_OFF threshold.
If any of the bits in the upper byte are set, NONE_OF_THE_ABOVE is asserted.
This command has two data bytes.
STATUS_VOUT
The STATUS_VOUT commands returns one byte with status information on VOUT.
Bit 0 of this command is undefined and reserved in the LTC3880.
The user is permitted to write a 1 to any bit in this command to clear a specific fault. This permits the user to clear
status by means other than using the CLEAR_FAULTS command.
Any supported fault bit in this command will initiate an ALERT event.
This command has one data byte.
STATUS_IOUT
The STATUS_IOUT commands returns one byte with status information on IOUT.
Only bits 7, 6, and 5 are supported in the LTC3880.
The user is permitted to write a 1 to any bit in this command to clear a specific fault. This permits the user to clear
status by means other than using the CLEAR_FAULTS command.
Any supported fault bit in this command will initiate an ALERT event.
This command has one data byte.
