3 说明

TPS2384 是一款四端口电源设备电源管理器 (PSEPM)，符合以太网供电 (PoE) IEEE 802.3af 标准。TPS2384 采用 48V 单电源供电并在较宽温度范围（–40°C 至 125°C）内工作。集成输出不需要每个端口两个外部元件（FET 和检测电阻），并可承受 100V 瞬态电压。四个单独的 15 位模数转换器用于测量端口电阻、电压、电流和芯片温度，从而使 PSE 解决方案简单而可靠。TPS2384 配备全面的软件解决方案，可满足苛刻的应用要求，而且可作为所有 PoE 系统设计的核心。

TPS2384 采用 64 引脚 PowerPAD™ (PAP) 封装（焊盘朝下）或 64 引脚 PowerPAD™ (PJD) 封装（焊盘朝上）。
