Table 13. Parametric Monitoring States
The VOUT_OV_FAULT_LIMIT command sets the value
of the output voltage that causes an output overvoltage
fault. The monitored voltage must drop by at least 2%
below the limit before the fault is allowed to clear. This
fault is masked until the output voltage is below this limit
for the first time. The 2 data bytes are in DIRECT for-
mat. In response to the VOUT_OV_FAULT_LIMIT being
exceeded, the device does the following:
1) Sets the VOUT_OV bit and the VOUT bit in STATUS_
2) Sets the VOUT_OV_FAULT bit in STATUS_VOUT.
3) Responds
4) Notifies the host through ALERT assertion (if enabled
The VOUT_OV_WARN_LIMIT command sets the value
of the output voltage that causes an output voltage high
warning. The monitored voltage must drop by at least 2%
below the limit before the warning is allowed to clear. This
warning is masked until the output voltage is below this
limit for the first time. This value is typically less than the
output overvoltage threshold in VOUT_OV_FAULT_LIMIT.
The 2 data bytes are in DIRECT format. In response to
the VOUT_OV_WARN_LIMIT being exceeded, the device
does the following:
1) Sets the VOUT bit in STATUS_WORD.
2) Sets the VOUT_OV_WARN bit in STATUS_VOUT.

The VOUT_UV_WARN_LIMIT command sets the value
of the output voltage that causes an output-voltage low
warning. The monitored voltage must increase by at
least 2% above the limit before the warning is allowed
to clear. This value is typically greater than the output
undervoltage fault threshold in VOUT_UV_FAULT_LIMIT.
This warning is masked until the output voltage reaches
the programmed VOUT_UV_WARN_LIMIT for the first
time and also during turn-off when the power supply
is disabled. The 2 data bytes are in DIRECT format. In
response to violation of the VOUT_UV_WARN_LIMIT, the
device does the following:
1) Sets the VOUT bit in STATUS_WORD.
2) Sets the VOUT_UV_WARN bit in STATUS_VOUT.
3) Notifies the host using ALERT assertion (if enabled in
The VOUT_UV_FAULT_LIMIT command sets the value of
the output voltage, which causes an output undervoltage
fault. The monitored voltage must increase by at least
2% above the limit before the fault is allowed to clear.
This fault is masked until the output voltage reaches the
programmed VOUT_UV_FAULT_LIMIT for the first time
and also during turn-off when the power supply is
disabled. The VOUT_UV_FAULT_LIMIT threshold is also
used to determine if TON_MAX_FAULT_LIMIT is exceed-
ed. The 2 data bytes are in DIRECT format. In response
