STATUS_VOUT (7Ah)
The STATUS_VOUT command is a standard PMBus ™ com-
mand that returns the value of the VOUT UV Warn flag.
Accesses to this command should use the PMBus ™ read
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
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-

byte protocol. To clear bits in this register, the underlying fault
should be removed and a CLEAR_FAULTS command is-
sued.
this register, the underlying fault should be removed and a
CLEAR_FAULTS command issued. The IN UV Warn flag will
default to 1 on startup. However, it will be cleared to 0 after
the first time the input voltage exceeds the resistor pro-
grammed UVLO threshold.

bits in this register, the underlying fault should be removed
and a CLEAR_FAULTS command issued.
