Detailed Description
The MAX34440 is a highly integrated system monitor
based upon a 16-bit MAXQM microcontroller with facto-
ry-programmed functionality to monitor up to six power
supplies. The device provides power-supply closed-loop
control, and local/remote thermal-sensing facilities.
The power-supply manager monitors the power-supply
output voltage and constantly checks for user-pro-
grammable overvoltage and undervoltage thresholds. It
also can margin the power-supply output voltage up or
down by a user-programmable level. The margining is
performed in a closed-loop arrangement, whereby the
device automatically 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 addition of an external current-sense
amplifier, the device can also monitor currents.
Thermal monitoring can be accomplished using up to
eight temperature sensors, including an on-chip ther-
mal sensor, four DS75LV digital thermometers, and a
MAX6695 dual remote/local thermal temperature sensor.
Communication with the DS75LV and MAX6695 tem-
perature sensors is conducted through a dedicated I2C/
SMBus interface.
The device provides ALERT and FAULT output signals.
Host communications are conducted through a PMBus-
compatible communications port. Address input con-
nections are also provided to allow up to four MAX34440
devices to reside on the system’s I/O bus.
