General Description

The Si3480 is a power manager intended for use with the Si3452 Power over Ethernet (PoE) controller.

The Si3480 enables the use of a smaller, lower cost, and more efficiently-utilized power supply in an unmanaged PoE Power Sourcing Equipment (PSE) system.

The Si3452 is capable of delivering over 30 W per port, which means that, in a typical 8-port system, a 240 W power supply would have to be used to avoid overload.

Key Features

  • Enables use of a smaller power.
  • Pin programmable for overall supply for a 4 or 8 port PoE power supply capacity, port system power level, port priority, and.
  • Self-contained solution operates detection timing without the need for a host for.
  • LED indication of port status and unmanaged operation overall power consumption.
  • No software required.
  • 20-pin Quad flat package.
  • No data isolation required (4x4 mm).
  • Fully compliant with IEEE 802.3.
