MAX34460

PMBus 12-Channel Voltage Monitor and Sequencer

General Description

Features

The MAX34460 is a system monitor that is capable of

managing up to 12 power supplies. The power-supply

manager monitors the power-supply output voltages and

constantly checks for user-programmable overvoltage

and undervoltage thresholds. If a fault is detected,

the device automatically shuts down the system in an

orderly fashion. The device can sequence the supplies

in any order at both power-up and power-down. With

the addition of external current DACs, the device has

the ability to close-loop margin the power-supply output

voltages up or down to a 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.
