These fault register bits latch upon a fault condition, and
must be reset manually by writing a zero to the register,
or by restarting the affected channel as described in the
Autoretry or Latched-Off Fault Management section.
FAULT_ Outputs
When an overcurrent event (fast-trip or slow-trip) causes
the MAX5961 to shut down the affected channel(s), a cor-
responding open-drain FAULT_ output is asserted low.
Note that the FAULT_ outputs are not asserted for shut-
downs caused by critical undervoltage or overvoltage.
The FAULT_ output is cleared when the channel is dis-
abled by pulling ON_ low or by clearing the Chx_EN1
or Chx_EN2 bits in register chxen.
ALERT Output
The ALERT output is an open-drain output that is assert-
ed low any time that a fault or other condition requiring
attention has occurred. The state of the ALERT output is
also indicated by bit 4 of the status3 register.
ALERT is the NOR of registers 0x5F, 0x63, 0x64, and 0x65,
so when the ALERT output goes low, the system microcon-
troller (C) should query these registers through the I2C
interface to determine the cause of the ALERT assertion.
