MAX34446：PMBus Power-Supply Data Logger
Detects and Records Out-of-Range Power-Supply Conditions to Determine Failure or Misuse
The MAX34446 data logger for power supplies can monitor voltages for overvoltage and undervoltage, as well as for overcurrent conditions and overtemperature conditions. The device constantly checks for userprogrammable thresholds; when these thresholds are exceeded, the device logs the recent real-time operating conditions in nonvolatile flash memory. The device can monitor up to four voltages or currents, and can monitor three temperature sensors. See the Typical Application Circuit/Block Diagram for more details.
