Analog Devices / Maxim Integrated MAX34441 5-Channel Power Supply Manager

Analog Devices MAX34441 5-Channel Power Supply Manager and intelligent fan controller is a PMBus™-compliant system-management controller IC incorporating comprehensive fault-logging and thermal-management capabilities for enterprise equipment. The MAX34441 combines five power-supply management channels with one channel of closed-loop fan control. This power-supply manager 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. The Analog Devices MAX34441 monitors power supply output voltages and constantly checks the user-programmable overvoltage and undervoltage thresholds. This device supports the capture of up to 15 failure logs in nonvolatile flash memory on user-defined fault events. The fan control channel allows the system fan to be operated at the minimum possible speed, minimizing power and acoustic noise while maximizing reliability through reduced fan wear and dust accumulation.
