Fault Dependency
If a fault event occurs (digital UV warning/critical, digital
OV warning/critical, or digital overcurrent warning), the
fault is logged by setting a corresponding bit in registers
fault0, fault1, or fault2 (see Tables 46, 47, and 48).
Likewise, circuit-breaker shutdown events are logged in
register status0[7:0] (see Table 49).
IFAULTS indicates the overcurrent status from slow com-
parator. IFAULTF indicates overcurrent status from fast
comparator. The status of FAULT reflects the OR opera-
tion of IFAULTS and IFAULTF.
These fault register bits latch upon a fault condition, and
must be reset manually by restarting as described in the
Latched-Off Fault Management section.
