MAX34440ETLA1+ Information

MAX34440 PMBus 6-Channel Power Supply Manager

Maxim Integrated's MAX34440 6-Channel Power-Supply Manager is aPMBus™-compliant, highly integrated system monitor based upon a 16-bitMAXQM microcontroller with factory-programmed functionality to monitorup to six power supplies. The device provides power-supply closed-loopcontrol, and local/remote thermal-sensing facilities. MAX34440 monitors the power-supply output voltage and continually checksfor user-programmable overvoltage and under voltage thresholds. ThisMaxim Integrated device can margin the power-supply outputvoltage up or down to a user-programmable level in a closed-looparrangement. The closed-loop arrangement allows the MAX34440 toautomatically adjust a pulse-width-modulated (PWM) output and thenmeasure the resulting output voltage. This Maxim Power-Supply Managercan also sequence the supplies in any order at both power-up andpower-down. Using an external current-sense amplifier, the MAX34440 6-Channel Power-Supply Manager can also monitorcurrents. This design makes the Maxim MAX344406-Channel Power-Supply Manager ideal for use in base stations, industrialcontrols, network switches/routers, servers, and smart grid networksystems.Learn More
