SI3480 Overview
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.
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
- 4x4 mm PCB footprint; RoHS clause 33 for Power over Ethernet compliant including the 802.3at amendment
- Extended operating temperature for higher power (30 W category 2 range (–40 to +85 °C) ports)
