MAX34461 PMBus 16-Channel Voltage Monitor and Sequ

Maxim Integrated's MAX34461 is a system monitor, capable of managing up to 16 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.

  • Supports up to five temperature sensors (one internal/four remote)
  • Expandable channel operation with parallel devices
  • Up to 16 GPOs
  • No external clocking required
  • 3.0 V to 3.6 V supply voltage
  • Base stations
  • Network switches/routers
  • Servers
  • Smart grid network systems
