MAX34451

PMBus 16-Channel V/I Monitor and

12-Channel Sequencer/Marginer

General Description

Beneﬁts and Features

The MAX34451 is a power-supply system manager

that 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. The system manager

monitors the power-supply output voltages and 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 the supplies in any

order at both power-up and power-down. 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.
