MAX34440
PMBus 6-Channel Power-Supply Manager
General Description
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.
