MAX34461
PMBus 16-Channel Voltage Monitor and Sequencer
General Description
The MAX34461 is a system monitor that is capable of
managing up to 16 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.
