PoE 供电设备 (PSE)

Analog Devices 的供电设备 (PSE) 控制器可支持多种以太网供电功率级别:IEEE PoE (13 W)、IEEE PoE+ (25.5 W) 和 ADI LTPoE++ (高达 90 W) 标准。PSE 控制器负责受电设备 (PD) 的检测和分级,以及通过以太网电缆向 PD 提供正确的功率量。我们的最新一代 PSE 控制器符合 IEEE 标准,采用 0.1 Ω 检测电阻器以降低功耗,并运用了一种高可靠性的 4 点 PD 检测方案以避免发生错误的 PD 检测。外部 MOSFET、一种可扩展的电缆放电保护方案、所有模拟引脚上的 80 V 绝对最大额定值、以及过热保护等均确保了稳健的运作。
