6-Channel, Flash-Configurable System Manager

with Nonvolatile Fault Registers

Table 17. Critical Fault Configuration

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

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).
