to violation of the VOUT_UV_FAULT_LIMIT, the device
does the following:
1) Sets the VOUT bit in STATUS_WORD.
2) Sets the VOUT_UV_FAULT bit in STATUS_VOUT.
3) Responds as specified in MFR_FAULT_RESPONSE.
4) Notifies the host using ALERT assertion (if enabled in
The OT_FAULT_LIMIT command sets the temperature,
in degrees Celsius, of the selected temperature sensor
at which an overtemperature fault is detected. The moni-
tored temperature must drop by at least 4NC below the
limit before the fault is allowed to clear. The 2 data bytes
are in DIRECT format. In response to the OT_FAULT_
LIMIT being exceeded, the device does the following:
1) Sets the TEMPERATURE bit in STATUS_WORD.
2) Sets the OT_FAULT bit in STATUS_TEMPERATURE
3) Responds
4) Notifies the host using ALERT assertion (if enabled in
The OT_WARN_LIMIT command sets the temperature,
in degrees Celsius, of the selected temperature sensor
at which an overtemperature warning is detected. The
monitored temperature must drop by at least 4NC below
the limit before the warning is allowed to clear. The 2
data bytes are in DIRECT format. In response to the
OT_WARN_LIMIT being exceeded, the device does the
following:
1) Sets the TEMPERATURE bit in STATUS_WORD.
2) Sets the OT_WARN bit in STATUS_TEMPERATURE
3) Notifies the host through ALERT assertion (if enabled
The POWER_GOOD_ON command sets the value of the
output voltage, which causes the PG output to assert. All
power supplies must be above their associated POWER_
GOOD_ON thresholds before the PG output is asserted.
Unused channels or disabled power supplies can use
the test mode described in the user note below to
force power good on the associated channel. All power

supplies must also be above POWER_GOOD_ON for
power-supply margining to begin. The POWER_GOOD_
ON level is normally set higher than the POWER_GOOD_
OFF level. The 2 data bytes are in DIRECT format.
USER NOTE: There is a special test mode that forces a
channel into and out of a power good state based on two
unique values. If either of these settings is configured into
POWER_GOOD_ON, the actual measured power-supply
voltage is ignored and the logical state is forced.

• Force power-good assert = POWER_GOOD_ON =
The POWER_GOOD_OFF command sets the value of
the output voltage that causes the PG output to deassert
after it has been asserted. Any power supply that falls
below the associated POWER_GOOD_OFF threshold
causes the PG output to be deasserted. The POWER_
GOOD_OFF level is normally set lower than the POWER_
GOOD_ON level. The 2 data bytes are in DIRECT format.

In the PMBus-sequencing configuration, TON_DELAY
sets the time, in milliseconds, from when a START
condition is received (a valid OPERATION command
or through the CONTROL pin when enabled) until the
PSENn output is asserted. In the timeslot-sequencing
configuration, TON_DELAY sets the time, in milliseconds,
from the beginning of a timeslot until the PSENn output
is asserted. The undervoltage fault and warning are
masked off during TON_DELAY. The 2 data bytes are in
DIRECT format.
The TOFF_DELAY sets the time, in milliseconds, from
when a STOP condition is received (a soft-off OPERATION
command or through the CONTROL pin when enabled)
until the PSENn output is deasserted. When commanded
to turn off immediately (either through the OPERATION
command or the CONTROL pin), the TOFF_DELAY value
is ignored. The 2 data bytes are in DIRECT format.
