以太网供电 (PoE) 接口控制器

Analog Devices 的以太网供电 (PoE) 产品包括了众多的供电设备 (PSE) 和受电设备 (PD) 控制器,可支持多种功率级别:IEEE PoE (13 W)、IEEE PoE+ (25.5 W)、IEEE PoE++ (71 W) 和 ADI LTPoE++ (高达 90 W) 标准。我们的 PSE 和 PD 控制器可提供完整的 PoE 解决方案,并采用外部组件 (例如:功率 MOSFET 和检测电阻器) 以降低电源通路中的电阻,从而最大限度减少热耗散并实现电源效率的最大化。此外,我们的坚固型电缆放电保护方案 (在所有的模拟引脚上提供一个很高的绝对最大额定值)、宽工作温度范围及过热保护皆有利于造就极为稳健的 PoE 解决方案,能够满足远远超过 ESD 和电缆 ESD 测试等级的 IEC61000 电缆放电要求。
