Maxim MAX34452ETN+

Overview

The MAX34451ETN+ is a PMBus 16-channel V/I monitor and 12-channel sequencer/marginer in 56 pin TQFN package. This power supply system manager is capable of monitoring up to 16 different voltage rails or currents and is also capable of sequencing and margining up to 12 power supplies. It monitors power supply output voltages/currents and constantly checks them for user programmable over and under threshold limits. If a fault is detected, the device automatically shuts down the system in an orderly fashion. The device can sequence supplies in any order at both power-up and power-down. It has ability to close loop margin power supply output voltages up or down to user programmable level. The device contains an internal temperature sensor and can support up to four external remote temperature sensors. Once configured, the device can operate autonomously without any host intervention. The MAX34451ETN+ is used in network switches/routers, base stations, servers and smart grid network systems.
