Data Sheet
POWER SUPPLY SYSTEM AND FAULT MONITORING
ADP1047/ADP1048
The ADP1047 / ADP1048 have extensive system and fault mon-
itoring capabilities. The system monitoring functions include
voltage, current, power, and temperature readings. The fault
conditions include out of limit for current, voltage, power, and
temperature. The limits for the fault conditions are programmable.
An extensive set of flags is set when certain thresholds or limits
FLAG CONVENTIONS
A flag indicates a fault condition; therefore, a flag is set (equal to
1, or high) when the fault or bad condition occurs. Good flags,
such as POWER_GOOD# and AC_OK, are active low flags. For
example, POWER_GOOD# = 1 indicates a problem.
Note that the signals relative to a flag are active high. For
example, if the POWER_GOOD# flag is set to 1, the PGOOD
pin is at Logic Level 0 because the POWER_GOOD# flag is
inverted at the pin to provide active high signals.
MANUFACTURER-SPECIFIC FLAGS
The manufacturer-specific flags are flags that are not covered by
the PMBus specification. Some flags simply indicate a condition
(typically, warning flags). The response to some of the flags is
individually programmable (typically, fault flags).
There is also a set of latched fault registers. These registers con-
tain the same flags, but the flags remain set to allow users to detect
an intermittent fault. Reading a latched register resets the flags
in that register. The latched fault registers are Register 0xFE80,
Register 0xFE81, and Register 0xFE82.
