Faults
The MAX16047/MAX16049 monitor the input (MON_)
channels and compare the results with an overvoltage
threshold, an undervoltage threshold, and a selectable
overvoltage or undervoltage early warning threshold.
Based on these conditions, the MAX16047/MAX16049
can assert various fault outputs and save specific infor-
mation about the channel conditions and voltages into
the nonvolatile EEPROM. Once a critical fault event
occurs, the failing channel condition, ADC conversions
at the time of the fault, or both may be saved by config-
uring the event logger. The event logger records a sin-
gle failure in the internal EEPROM and sets a lock bit
which protects the stored fault data from accidental
erasure on a subsequent power-up.
The MAX16047/MAX16049 are capable of measuring
overvoltage and undervoltage fault events. Fault condi-
tions are detected at the end of each ADC conversion.
An overvoltage event occurs when the voltage at a
monitored input exceeds the overvoltage threshold for
that input. An undervoltage fault occurs when the volt-
age at a monitored input falls below the undervoltage
threshold. Fault thresholds are set in registers r23h to
r46h as shown in Table 15. Disabled inputs are not
monitored for fault conditions and are skipped over by
the input multiplexer. Only the upper 8 bits of a conver-
sion result are compared with the programmed fault
thresholds.
The general-purpose inputs/outputs (GPIO1–GPIO6)
can be configured as Any_Fault outputs or dedicated
FAULT1
and
FAULT2
outputs to indicate fault condi-
tions. These fault outputs are not masked by the critical
fault enable bits shown in Table 17. See the General-
Purpose Inputs/Outputs section for more information on
configuring GPIOs as fault outputs.
