APPENDIX C: PMBUS COMMAND DETAILS
STATUS_VOUT
The STATUS_VOUT command returns one byte of VOUT status information.
STATUS_VOUT Message Contents:
BIT
MEANING
7
VOUT overvoltage fault.
6
VOUT overvoltage warning.
5
VOUT undervoltage warning.
4
VOUT undervoltage fault.
3
VOUT_MAX warning.
2
TON_MAX fault.
1
TOFF_MAX warning.
0
Not supported by the LTM4686B (returns 0).
ALERT can be asserted if any of bits[7:1] are set. These may be cleared by writing a 1 to their bit position in STATUS_VOUT, in lieu of a CLEAR_FAULTS
command.
This command has one data byte.
STATUS_IOUT
The STATUS_IOUT command returns one byte of IOUT status information.
STATUS_IOUT Message Contents:
BIT
MEANING
7
IOUT overcurrent fault.
6
Not supported (LTM4686B returns 0).
5
IOUT overcurrent warning.
4:0
Not supported (LTM4686B returns 0).
ALERT can be asserted if any supported bits are set. Any supported bit may be cleared by writing a 1 to that bit position in STATUS_IOUT, in lieu of a
CLEAR_FAULTS command.
This command has one data byte.
STATUS_INPUT
The STATUS_INPUT command returns one byte of VIN (SVIN) status information.
STATUS_INPUT Message Contents:
BIT
MEANING
7
SVIN overvoltage fault.
6
Not supported (LTM4686B returns 0).
5
SVIN undervoltage warning.
4
Not supported (LTM4686B returns 0).
3
Unit off for insufficient SVIN voltage.
2
Not supported (LTM4686B returns 0).
1
Input over current warning.
0
Not supported (LTM4686B returns 0)
ALERT can be asserted if bit 7 is set. Bit 7 may be cleared by writing it to a 1, in lieu of a CLEAR_FAULTS command.
