What Is a Fault Log?
A fault log is a non-volatile record of the power system
leading up to the time of fault. It holds the most recent
monitored values (uptime, voltage, current, temperature)
that can be analyzed to help determine the cause of the
fault. It is a powerful diagnostic feature of each of the
digital power managers on the DC1962C demo board.
Create a Fault and Fault Log
To create a fault log, you must create a fault, as described
in the Creating a Fault on page 8. Select the appropriate
device in the system tree by clicking on the U1 LTC2974
chip. We will proceed to work with the LTC2974 fault log.
