n/a
VIN_UV_WARN_LIMIT (58h)
The VIN_UV_WARN_LIMIT is a standard PMBus com-
mand that allows configuring or reading the threshold for the
VIN Under-voltage Warning detection. Reading and writing to
this register should use the coefficients shown in the Teleme-
try and Warning Conversion Coefficients Table. Accesses to
this command should use the PMBus read or write word
protocol. If the measured value of VIN falls below the value in
this register, VIN UV Warn flags are set in the respective reg-
isters, and the SMBA signal is asserted.
TABLE 8. VIN_UV_WARN_LIMIT Register

Default
1h – 0FFFh

0000h (disabled)
0000h

STATUS_BYTE (78h)
The STATUS_BYTE command is a standard PMBus com-
mand that returns the value of a number of flags indicating the
state of the LM25066. Accesses to this command should use
the PMBus read byte protocol. To clear bits in this register,
the
underlying
fault
should
be
removed
and
a
CLEAR_FAULTS command issued.

STATUS_WORD (79h)
The STATUS_WORD command is a standard PMBus com-
mand that returns the value of a number of flags indicating the
state of the LM25066. Accesses to this command should use
the PMBus read word protocol. To clear bits in this register,
the
underlying
fault
should
be
removed
and
a
CLEAR_FAULTS command issued. The INPUT and VIN UV
FAULT flags will default to 1 on startup. However, they will be
cleared to 0 after the first time the input voltage exceeds the
resistor programmed UVLO threshold.
