STATUS_VOUT (7Ah)
The STATUS_VOUT command is a standard PMBus com-
mand that returns the value of the VOUT UV Warn flag.
STATUS_INPUT (7Ch)
The STATUS_INPUT command is a standard PMBus com-
mand that returns the value of a number of flags related to
input voltage, current, and power. Accesses to this command
should use the PMBus read byte protocol. To clear bits in this
STATUS_TEMPERATURE (7dh)
The STATUS_TEMPERATURE is a standard PMBus com-
mand that returns the value of the of a number of flags related
to the temperature telemetry value. Accesses to this com-

Accesses to this command should use the PMBus read byte
protocol. To clear bits in this register, the underlying fault
should be cleared and a CLEAR_FAULTS command issued.
register, the underlying fault should be cleared and a
CLEAR_FAULTS command issued. The VIN UV Warn flag
will default to 1 on startup, however, it will be cleared to 0 after
the first time the input voltage increases above the resistor-
programmed UVLO threshold.
