PMBus 5-Channel Power-Supply Manager
and Intelligent Fan Controller
General Description
The MAX34441 is a complex system monitor that can man-
age up to five power supplies and a fan. 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-programma-
ble level. The margining is performed in a closed-loop
arrangement whereby the device automatically adjusts
a pulse-width-modulated (PWM) output and then mea-
sures 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.
The device also contains closed-loop fan-speed control.
Based on user-programmable settings for fan-control
PWM duty cycles or RPM speeds at particular tempera-
ture breakpoints, the device automatically adjusts the fan
speed in a manner to reduce audible noise and power
consumption.
