PMBus Power-Supply Data Logger
STATUS_BYTE (78h)
The STATUS_BYTE command returns 1 byte of information with a summary of the most critical faults. A value of 1
indicates that a fault or warning event has occurred and a 0 indicates otherwise. Bits for unsupported features are
reported as 0. The STATUS_BYTE cannot be restored by RESTORE_DEFAULT_ALL command. Table 10 describes the
STATUS_BYTE message content. This command is read-only.

These bits always return a 0.
An overvoltage fault has occurred.
An overcurrent fault has occurred.
This bit always returns a 0.
A temperature fault or warning has occurred.
A communication, memory, or logic fault has occurred.
A fault or warning not listed in bits [7:1] has occurred.
STATUS_WORD (79h)
The STATUS_WORD command returns 2 bytes of information with a summary of the reason for a fault. The low byte of
the STATUS_WORD is the same data as the STATUS_BYTE. Table 11 describes the STATUS_WORD message content.
