MFR_COMMON
The MFR_COMMON command contains status bits that are common to multiple LTC PMBus products.
MFR_COMMON Message Contents:
BIT
MEANING
7
LTC3882-1 not forcing
ALERT
low.
6
LTC3882-1 not BUSY.
5
LTC3882-1 calculations not pending.
4
LTC3882-1 output not in transition.
3
LTC3882-1 EEPROM initialized.
2
Not supported (LTC3882-1 returns 0).
1
SHARE_CLK timeout.
0
Not supported (LTC3882-1 returns 0).
This read-only command has one data byte.
MFR_INFO
The MFR_INFO command contains additional status bits that are LTC3882-1-specific and may be common to multiple
LTC PSM products.
MFR_INFO Data Contents:
BIT
MEANING
15:6
Reserved.
5
EEPROM ECC status.
0: Corrections have been made in the EEPROM user space.
1: No corrections have been made in the EEPROM user space.
4:0
Reserved
EEPROM ECC status is updated after each RESTORE_USER_ALL or RESET command, a power-on reset or an EEPROM
bulk read operation. This read-only command has two data bytes.
CLEAR_FAULTS
The CLEAR_FAULTS command clears any fault bits that have been set and deasserts (releases) the
ALERT
pin. This
command clears all bits in all status commands simultaneously.
CLEAR_FAULTS does not cause a channel that has latched off for a fault condition to restart. Channels that are latched
off for a fault condition are restarted when the output is commanded to turn off and then on through the OPERATION
command or RUN pins, or IC supply power is cycled.
If a fault is still present when CLEAR_FAULTS is commanded, that fault bit will immediately be set and
ALERT
again
asserted low.
This write-only command has no data bytes.
