The MAX34446 data logger for power supplies canmonitor voltages for overvoltage and undervoltage, aswell as for overcurrent conditions and overtemperatureconditions. The device constantly checks for userprogrammablethresholds; when these thresholds areexceeded, the device logs the recent real-time operatingconditions in nonvolatile flash memory. The device canmonitor up to four voltages or currents, and can monitorthree temperature sensors.
