MAX34440  
PMBus 6-Channel Power-Supply Manager  
General Description  
Features  
S 6 Channels of Power-Supply Management  
The MAX34440 is a complex system monitor that can  
manage up to six power supplies. The power-supply  
manager monitors the power-supply output voltage and  
constantly checks for user-programmable overvoltage  
and undervoltage thresholds. It can also margin the  
power-supply output voltage up or down to a user-  
programmable level. The margining is performed in a  
closed-loop arrangement whereby the device automati-  
cally adjusts a pulse-width-modulated (PWM) output and  
then measures the resultant output voltage. The power-  
supply manager can also sequence the supplies in any  
order at both power-up and power-down. With the addi-  
tion of an external current-sense amplifier, the device  
can also monitor currents.
