ADIN1110集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

ADIN1110屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由亞德諾半導體技術有限公司制造生產(chǎn)的ADIN1110驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

DESCRIPTION

The LTC?9111 is an IEEE 802.3cg compliant Single-Pair

Power over Ethernet (SPoE) Powered Device (PD) controller.

A wide 2.3V to 60V operating range capability with

polarity correction make the LTC9111 particularly well

suited for classification-based systems in building and

factory automation.

SCCP-based classification ensures full operating voltage

is applied by the Power Sourcing Equipment (PSE) only

when a valid PD is connected. The LTC9111 drives two

external N-channel MOSFET switches during classification

with micropower operation to minimize reservoir capacitor

requirements. An external N-channel MOSFET switch

isolates the output capacitance from the connector during

classification and inrush. A voltage supervisor enables the

external MOSFET when the PD input voltage exceeds the

ON voltage threshold for the configured class and after a

mandated delay. The EN output asserts after the controlled

GATE pin ramp-up. The MOSFET is disabled if the input

voltage drops below the OFF voltage threshold for the

configured class. The LTC9111 drives a pair of external

low-side N-channel MOSFETs with a low start-up voltage

of 1.6V for polarity correction with reduced power losses.
