DESCRIPTION
Sequencer state where the fault has happened (see Table 1 for state codes).
Fault has happened during power-up if bit [3] = 0 and during power-down if [3] = 1.
Bits [2:0] indicate the slot number.
Not used
Fault log triggered on MON1 falling below its undervoltage threshold
Fault log triggered on MON2 falling below its undervoltage threshold
Fault log triggered on MON3 falling below its undervoltage threshold
Fault log triggered on MON4 falling below its undervoltage threshold
Fault log triggered on MON5 falling below its undervoltage threshold
Fault log triggered on MON6 falling below its undervoltage threshold
Not used
Fault log triggered on MON1 exceeding its overvoltage threshold
Fault log triggered on MON2 exceeding its overvoltage threshold
Fault log triggered on MON3 exceeding its overvoltage threshold
Fault log triggered on MON4 exceeding its overvoltage threshold
Fault log triggered on MON5 exceeding its overvoltage threshold
Fault log triggered on MON6 exceeding its overvoltage threshold
Fault log triggered on EXTFAULT
Not used
MON1 ADC output (8 MSBs)
MON2 ADC output (8 MSBs)
MON3 ADC output (8 MSBs)
MON4 ADC output (8 MSBs)
MON5 ADC output (8 MSBs)
MON6 ADC output (8 MSBs)
Autoretry/Latch Mode
The MAX16067 can be configured for one of two fault
management methods: autoretry or latch-on-fault. Set
r74h[4:3] to ‘00’ to select the latch-on-fault mode. In
this configuration, EN_OUT_s deassert after a critical
fault event. The device does not reinitiate the power-up
sequence until EN is toggled or the software enable bit
is toggled. See the Enable Input (EN) section for more
information on setting the software enable bit.
Set r74h[4:3] to a value other than ‘00’ to select autoretry
mode (see Table 19). In this configuration, the device
shuts down after a critical fault event then restarts fol-
lowing a configurable delay. Use r74h[2:0] to select an
autoretry delay from 20ms to 1.6s. See Table 19 for more
information on setting the autoretry delay.
When fault information is stored in flash (see the Critical
Faults section) and autoretry mode is selected, set an
autoretry delay greater than the time required for the
storing operation. When fault information is stored in
flash and latch-on-fault mode is chosen, toggle EN or
reset the software enable bit only after the completion of
the storing operation. When saving information about the
failed lines only, ensure a delay of at least 12ms before
the restart procedure. Otherwise, ensure a minimum
153ms timeout, to ensure that ADC conversions are
completed and values are stored correctly in flash.
