Efficient, intelligent and cost-effective balancing of powered device (PD) loads is a critical design consideration for multi-port PoE equipment. Complementing Silicon Labs’ popular Si3452 PSE controllers, Silicon Labs’ PoE power management ICs provide an easy-to-use, energy-efficient and small-footprint solution for streamlining power delivery in managed and unmanaged switches and routers, iPBXs, IP-based security systems, set-top boxes and power injectors.
Silicon Labs’ Si348x power management ICs take advantage of the real-time voltage and current monitoring capabilities of the Si3452 PoE controller to apply active power management based on actual consumption, enhancing the efficient use of switch ports beyond simple classification schemes.
Silicon Labs offers a complete suite of development tools including a graphical user interface (GUI)-based software development tool to enable quick evaluation and design with the Si348x ICs and companion Si3452 devices. The Si3480MS8-KIT development kit implements an 8-port midspan power injector with an intelligent power management LED display, enabling detailed evaluation of the Si3452 in conjunction with the Si3480 8-port power manager. The 24-port SmartPSE24-KIT power management evaluation kit supports SPI or UART-based interfaces and includes comprehensive power management functions to simplify designing with the Si3482 IC.
Features
Enables use of a smaller power supply for up to 48-port PoE systems
Operates without the need for a host for unmanaged operation
Supports classification-based and LLDP power negotiation
Supports individual port priority and port configuration
Fully-compliant with IEEE 802.3 clause 33 for PoE including the 802.3at amendment for higher power (30 W, category 2 ports)
LED indication of port status and overall power consumption
Pin-selectable SPI or UART interface and UART data rate
Pin programmable for overall power supply capacity, port power level, port priority, and detection timing
20- or 24-pin QFN, 4x4 mm PCB footprint; RoHS complaint
Extended operating temperature range (–40 to +85 °C)
