Maxim MAX34440 PMBus 6-Channel Power Supply Manager

Maxim Integrated's MAX34440 6-Channel Power-Supply Manager is a PMBus™-compliant, highly integrated system monitor based upon a 16-bit MAXQM microcontroller with factory-programmed functionality to monitor up to six power supplies. The device provides power-supply closed-loop control, and local/remote thermal-sensing facilities. MAX34440 monitors the power-supply output voltage and continually checks for user-programmable overvoltage and under voltage thresholds. This Maxim Integrated device can margin the power-supply output voltage up or down to a user-programmable level in a closed-loop arrangement. The closed-loop arrangement allows the MAX34440 to automatically adjust a pulse-width-modulated (PWM) output and then measure the resulting output voltage. This Maxim Power-Supply Manager can also sequence the supplies in any order at both power-up and power-down. Using an external current-sense amplifier, the MAX34440 6-Channel Power-Supply Manager can also monitor currents. This design makes the Maxim MAX34440 6-Channel Power-Supply Manager ideal for use in base stations, industrial controls, network switches/routers, servers, and smart grid network systems.
