DEMO MANUAL DC1697A
SOFTWARE SETUP
Figure 6.
The DC1697A control panel was designed to allow the user
to quickly evaluate the LTC2945. The user has the ability
to set fault thresholds, enable/disable and clear alerts as
well as change the source for the VIN measurement. Rsens
is set to 20mΩ by default on the DC1697A, should any
changes be made to the board, the corresponding value
should be entered into the software GUI. By pressing
RUN, the software interface will begin using the DC590
for data collection.
The Alert Persist option modifies how the ALERT pin and
LED on the board react. With Alert Persist checked, on
an ALERT the corresponding FAULT button will light up
red on the software GUI. The ALERT LED should also be
red on the DC1697A itself. Click the Clear Alerts button
to clear all alerts.
With Alert Persist not enabled, an alert event will still light
up the corresponding FAULT button, however the ALERT
LED on the board will turn on briefly before turning off due
to a read by the GUI from the Fault Register. The QuikEval
GUI constantly polls registers in order to properly graph
and monitor the part. In a real world situation,
these re-
peated reads are not necessary. The Alert Persist option
was designed to simulate real world behavior while still
providing a friendly interface.
