Warning thresholds, temperature fault threshold, protection
ranges, fault masking, and averaging can be configured in the
Device Configuration panel. The first tab of this panel, shown
in 

, is enabled by clicking the gear icon shown on the

LM25056 block representation.

The Warning and Fault Threshold tab allows configuration of
the input under voltage, input over voltage, output under volt-
age, input over current, input power, and over temperature
warnings. This tab also allows adjustment of the over tem-
perature fault threshold. Fault threshold for the current limit
and power limit are set by the hardware design based on the
sense resistor. Decimal values for the thresholds are shown
in the text box located to the right of the slider bar. Above the
decimal values setting is the value of the setting in hexadec-
imal; which can be useful when developing software for this
device.
The Fault Behavior tab shown in 

set the device fault and warning configuration and masking.
By selecting Fault Masking, it allows individual faults and
warnings to be masked and not be shown as an SMBus alert.
Faults and warnings that only issue a SMBus alert allow
masking of the alert.

The Averaging tab allows the user to set the value of the
MFR_SAMPLES_FOR_AVG register of the LM25056 and
sets the number of samples averaged for telemetry of VIN,
IIN, PIN and VAUX. This is selectable from 1 to 4096 in pow-
ers of 2. Detail of the Averaging tab is shown below in 

.

For convenience, the Device Configuration Panel can be un-
docked by holding down the left mouse button while the cursor
is at the top of the panel and dragging it to where you would
like it to be placed.
