描述：IP804A
IP804A 是用于 PoE（以太網供電）系統的 4 端口 PSE（供電設備）控制器 IC。它將電源、模擬和邏輯電路集成到單個芯片中，可用于中型和端點 PSE 應用。IP804A 滿足所有 IEEE 802.3AF-2003 要求，例如多點電阻檢測、PD 分類、DC 斷開和 Midcap 的回退。它還滿足所有 IEEE 802.3AT-2009 要求，例如兩事件分類，并為每個端口提供最大 36W 的功率。
IP804A 包括內部溫度監控和熱保護，以防止結過熱。內置 3.3V 穩壓器以支持外部設備。多個IP804A可以集成構建一個4×N端口PSE系統，I2C總線用于從每個IP804A收集PD電源狀態以支持全局電源管理。
多個 IP804A 可以構建一個經濟高效的 PHY 級 PSE 系統，以支持 PD 分類和電源管理，無需主機。有了管理主機，就可以構建一個基于網絡的LLDP（鏈路層發現協議）的多個IP804As PSE系統。基于 LLDP（IEEE Std 802.3AT-2009 的一部分），可以實時維護 PSE 和 PD 之間的動態電源管理以提高電源效率。
管理交換機主機可以選擇通過 I2C 總線與 IP804A 通信以進行 PSE 管理活動。可以實施光耦合器以在主機和 IP804A 之間提供電氣隔離以進行信號通信。
