LTC4279規(guī)格書詳情
LTC4279屬于集成電路（IC）的以太網(wǎng)供電（PoE）控制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LTC4279以太網(wǎng)供電（PoE）控制器以太網(wǎng)供電 (PoE) 控制器允許設(shè)計(jì)人員通過單個以太網(wǎng)連接傳輸電流和數(shù)據(jù)。遠(yuǎn)程設(shè)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(rèn)證。
DESCRIPTION
The LTC?9101-2 chipset is a 12/24-port power sourcing
equipment (PSE) controller designed for use in IEEE 802.3bt
Type 3 and 4 compliant Power over Ethernet (PoE) systems.
The LTC9101-2/LTC9102 is designed to power compliant
802.3af, 802.3at, and 802.3bt PDs. The LTC9101-2/LTC9102
chipset delivers lowest-in-industry heat dissipation by utilizing
low RDS(ON) external MOSFETs and 0.1Ω sense resistance
per power channel. A transformer-isolated communication
protocol replaces expensive opto-couplers and complex isolated
3.3V supply, resulting in significant BOM cost savings.
Advanced power management features include per-port
14?bit current/voltage monitoring, programmable power
limits, and versatile fast shut down of preselected ports.
An advanced power management host software layer is
available. PD detection uses a proprietary multipoint detection
mechanism ensuring excellent immunity from false PD
identification. Autoclass and 5-event physical classification
are supported. The LTC9101-2/LTC9102 includes an
I2C serial interface operable up to 1MHz. The LTC9101-2/
LTC9102 is pin or I2C programmable to negotiate PD delivered
power up to 71.3W.
