LTC4278規(guī)格書詳情
LTC4278屬于集成電路（IC）的以太網(wǎng)供電（PoE）控制器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的LTC4278以太網(wǎng)供電（PoE）控制器以太網(wǎng)供電 (PoE) 控制器允許設計人員通過單個以太網(wǎng)連接傳輸電流和數(shù)據(jù)。遠程設備通過以太網(wǎng)電纜供電，因此無需電池、本地電源適配器和其他電源電纜。橋式整流器和 N+1 O-Ring 是兩種 PoE 控制器類型。可用特性可能包括 N 和 P 溝道 FET、內(nèi)部開關(guān)和汽車認證。
DESCRIPTION
The LTC?9101-3/LTC9103 chipset is a 8/16-port power
sourcing equipment (PSE) controller and power manager
designed for use in IEEE 802.3at compliant Power
over Ethernet (PoE) systems. The LTC9101-3 manages a
user-defined system-level power budget across all ports.
Port power is automatically assigned based on system
power availability, initial physical classification and after
power up, port dynamic power consumption.
The LTC9101-3 prioritizes port power by port number (port 1
is highest priority) and automatically removes power from
lower priority ports to accommodate higher priority ports.
The LTC9101-3 features an interface to control an external
serial LED driver. LED indications include Port On, Port
Off, Port Power Denied, and Port Fault states. A Supply
Overload LED indicates system power usage is near
power limit or a port is being denied power.
The LTC9101-3 operates without a host present.
Configuration is accomplished by pin settings and I2Cbased
flash programming.
The LTC9101-3 autonomously performs compliant
802.3at detection, classification power up, power on, and
fault management.
