MAX34446_12 Datasheet, PDF (1/36 Pages) Maxim Integrated Products – PMBus Power-Supply Data Logger

EVALUATION KIT AVAILABLE
MAX34446
PMBus Power-Supply Data Logger
General Description
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 user-
programmable 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.
