MAX34446
PMBus Power-Supply Data Logger
If the device is not enabled to measure either current or voltage, or if a temperature sensor is disabled, the associated
fault-log byte position returns 0000h.
There is a FAULT_LOG_COUNT (16-bit counter) at the beginning of each fault log that indicates which fault log is
the latest. This counter rolls over should more than 65,535 faults be logged. This counter is not cleared when the
CLEAR_NV_FAULT_LOG bit in MFR_MODE is toggled. Table 19 describes the 255 bytes returned by the
MFR_NV_FAULT_LOG command.
USER NOTE: V DD must be above 2.9V for the device to clear or log data into MFR_NV_FAULT_LOG. During
a write to the fault log, the device temporarily stops monitoring and does not respond to SMBus commands.
