MAX34462
PMBus 16-Channel Monitor/Sequencer with
Differential Inputs and Margining DACs
General Description
The MAX34462 is a system monitor that can manage
up to 16 power supplies. The power-supply manager
monitors the power-supply output voltages and con-
stantly checks for user-programmable overvoltage and
undervoltage thresholds. If a fault is detected, the device
automatically shuts down the system in an orderly fash-
ion. The device can sequence the supplies in any order
at both power-up and power-down. The device contains
16 independent voltages DACs, which the device uses 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.
