PoE 供电设备 (PSE)

Analog Devices 供电设备 (PSE) 控制器支持多个功率级的以太网供电:IEEE PoE(13W,802.3af)、IEEE PoE+(25.5W,802.3at)、IEEE PoE++(71.3W,802.3bt)和 ADI LTPoE++ (90W) 标准。PSE 控制器负责检测受电器件 (PD) 并对其分类,以及通过以太网电缆向 PD 供应适当量的电力。我们的最新一代 PSE 控制器符合 IEEE 标准,使用 0.15 Ω 检测电阻来降低功耗,并使用高可靠性的 4 点 PD 检测方案来消除错误 PD 检测。外部 MOSFET、可扩展的电缆放电保护方案、所有模拟引脚上 80 V 的绝对最大额定值以及过热保护共同确保了可靠运行。
