6-Channel, Flash-Configurable System Manager
with Nonvolatile Fault Registers
Critical Faults
During normal operation, a fault condition can be con-
figured to shut down all the EN_OUT_s and store fault
information in the flash memory by setting the appro-
priate critical fault enable bits. During power-up and
power-down, all sequenced MON inputs are considered
critical. Faults during power-up and power-down always
cause the EN_OUT_s to turn off and can store fault infor-
mation in the flash memory, depending on the contents
of r6Dh[1:0]. Set the appropriate critical fault enable bits
in registers r6Eh–r72h (see Table 17) for a fault condition
to trigger a critical fault.
Logged fault information is stored in flash registers
r200h–r208h (see Table 18). After fault information is
Table 17. Critical Fault Configuration
logged, the flash is locked and must be unlocked to
enable a new fault log to be stored. Write a ‘0’ to r8Ch[1]
to unlock the configuration flash. Fault information can
be configured to store ADC conversion results and/or
fault flags in registers. Select the critical fault configura-
tion in r6Dh[1:0]. Set r6Dh[1:0] to ‘11’ to turn off the fault
logger. All stored ADC results are 8 bits wide (MSBs of
the conversion).
Power-Up/Power-Down Faults
All EN_OUT_s deassert when an overvoltage or under-
voltage fault is detected during power-up/power-down
and the MAX16067 enters to the fault state. Fault infor-
mation can be stored to flash depending on r6D[1:0]
(see Table 17).
