Power-Up/Power-Down Faults
All EN_OUTs are deasserted if an overvoltage or under-
voltage fault is detected during power-up/power-down.
Under these conditions, information of the failing slot is
stored in EEPROM r00h[3:0] unless r47h[1:0] is set to
‘11’ (see Table 23).
If there is a tracking fault on a channel configured for
closed-loop tracking, a fault log operation occurs and
the bits representing the failed tracking channels are
set to ‘0’ unless r47h[1:0] is set to ‘11’ (see Table 24).
Autoretry/Latch Mode
For critical faults, the MAX16046/MAX16048 can be
configured for one of two fault management methods:
autoretry or latch-on-fault. Set r4Fh[3] to ‘0’ to select
autoretry mode. In this configuration, the device will
shut down after a critical fault event then restart follow-
ing a configurable delay. Use r4Fh[2:0] to select an
autoretry delay from 20μs to 1.6s. See Table 25 for
more information on setting the autoretry delay.
Set r4Fh[3] to ‘1’ to select the latch-on-fault mode. In
this configuration EN_OUT_s are deasserted after a
critical fault event. The device does not re-initiate the
power-up sequence until EN is toggled or the
Software
Enable
bit is reset to ‘0.’ See the Enable section for
more information on setting the
Software Enable
bit.
If fault information is stored in EEPROM (see the Critical
Faults section) and autoretry mode is selected, set an
autoretry delay greater than the time required for the
storing operation. If fault information is stored in
EEPROM and latch-on-fault mode is chosen, toggle EN
or reset the
Software Enable
bit only after the comple-
tion of the storing operation. If saving information about
the failed lines only, ensure a delay of at least 60ms
before the restart procedure. Otherwise, ensure a mini-
mum 204ms timeout. This ensures that ADC conver-
sions are completed and values are stored correctly in
EEPROM. See Table 26 for more information about
required fault log operation periods.
