LTC4271規(guī)格書詳情

LTC4271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LTC4271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??捎锰匦钥赡馨?N 和 P 溝道 FET、內(nèi)部開關和汽車認證。

DESCRIPTION

The LTC?9101-2A/LTC9102 chipset is a (up to) 48-port power

sourcing equipment (PSE) controller designed for use in IEEE

802.3at Type 1 and 2 compliant Power over Ethernet (PoE) systems.

The LTC9101-2A/LTC9102 is designed to power compliant

802.3af and 802.3at PDs. The LTC9101-2A/LTC9102 chipset delivers

lowest-in-industry heat dissipation using low RDS(ON) external

MOSFETs and 0.1Ω sense resistance per power channel. A transformer-

isolated communication protocol replaces expensive optocouplers

and a complex isolated 3.3V supply, resulting in significant

bill of materials (BOM) cost savings.

Advanced power management features include per-port 14?bit current/

voltage monitoring, programmable current limits, and versatile

fast shutdown of preselected ports. PD detection uses a proprietary

multipoint detection mechanism, ensuring excellent immunity from

false PD identification. 1-event and 2-event physical classification

are supported. The LTC9101-2A/LTC9102 includes an I2C serial

interface operable up to 1MHz. The LTC9101-2A/LTC9102 is pin or

I2C programmable to negotiate PD-delivered power up to 25.5W.
