描述 Description

Microsemi’s™ PD69208M Power over Ethernet (PoE) and Power over HDBaseT (PoH) Manager chip integrates power, analog, and state of the art Logic into a single 56-pin, plastic QFN package. The device is used in Ethernet switches and Midspans to allow network devices to share power and data over the same cable. PD69208M device is an 8 ports, mixed-signal, high voltage PoE/PoH PSE Manager. The PD69208M supports standard PD (Powered Device) detection, power-up, and protection according to IEEE802.3 and the HDBaseT standards as well as legacy/pre-standard PD detection. The PD69208M provides PD real time protection through the following mechanisms: overload, under-load, over-voltage, over temperature, and short-circuit and enables operation in a total standalone mode, with no need for interaction by the host processor. The PD69208 executes all real time functions as specified in IEEE802.3at High Power (“AT”) and PoH standards, including load detection, “AF”, “AT”, and PoH classification; using Multiple Classification Attempts (MCA). The PD69208M supports supply voltages between 32V and 57V with no need of additional power supply sources. A system that powers over 4 pairs (twin PSE) can be implemented, based on 2 ports of PD69208M – enabling an extra feature for simple and low cost high power PD device. PD69208M support up to Type-3 PSE (60W). An on-going monitoring of system parameters for the host software is available. Internal thermal protection is implemented in the chip. PD69208M is a low power device that uses internal MOSFETs and internal sense resistors.  ROHS, PB Free

简介

PD69208MILQ-TR属于集成电路（IC）的以太网供电（PoE）控制器。由制造生产的PD69208MILQ-TR以太网供电（PoE）控制器以太网供电 (PoE) 控制器允许设计人员通过单个以太网连接传输电流和数据。远程设备通过以太网电缆供电，因此无需电池、本地电源适配器和其他电源电缆。桥式整流器和 N+1 O-Ring 是两种 PoE 控制器类型。可用特性可能包括 N 和 P 沟道 FET、内部开关和汽车认证。
