Maxim Integrated MAX34441 Power Supply Manager
and Intelligent Fan Controller

Provides Unparalleled "Black Box" Failure Logging

Maxim Integrated's MAX34441 5-channel power supply manager and intelligent fan controller is a PMBus™-compliant system-management controller IC incorporating the industry's most comprehensive fault-logging and thermal-management capabilities for enterprise equipment. The Maxim Integrated MAX34441 combines five power-supply management channels with one channel of the most sophisticated closed-loop fan control available. The MAX34441 monitors power supply output voltages and constantly checks the user-programmable overvoltage and undervoltage thresholds.

This Maxim Integrated device supports the capture of up to 15 failure logs in nonvolatile flash memory on user-defined fault events. The MAX34441 ensures predictable power-supply operation, improves system performance, and extends energy efficiency in complex systems, such as network switches and routers, base stations, and servers, as well as high-reliability industrial and medical equipment.
