EVALUATION KIT AVAILABLE  
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.
