Reliably protect and multiplex your power paths

parametric-filter檢視所有產品
Our input power protection portfolio offers a comprehensive selection of integrated ICs and external-FET controllers for protecting power paths. eFuses and hot-swap controllers provide scalable solutions for overvoltage, short-circuit and inrush current control. Ideal diode controllers and select eFuses protect against reverse current and reverse polarity events. Integrated power muxes, along with other reverse current blocking solutions, protect power paths during switchover events. Whether for enterprise data centers, automotive ADAS, industrial control systems, or PCs and personal electronics, TI has a protection solution for your power path.

參考設計
適用於 48V 人工智慧伺服器的 8kW 熱插拔參考設計

隨著人工智慧 (AI) 和機器學習 (ML) 進步,企業伺服器也漸趨耗電,因為這些伺服器需同時處理大量資料和儲存。每個伺服器主板的穩定狀態額定功率上升到 5kW 至 6kW,相較之下,一般伺服器則為 1kW 至 2kW。然而其外形尺寸卻維持不變,這也讓更高的功率密度帶來了系統設計挑戰。與一般伺服器相比,AI 伺服器的負載幅度、電壓轉換速率和暫態負載頻率增加了三到四倍。考慮到這些需求,此參考設計使用 LM5066I 熱插拔控制器開發,可在額定輸入電壓為 54V 的高功率伺服器背板系統中,提供穩健且可靠的輸入電源路徑保護設計。

參考設計
車用離電池處理器電源參考設計,適用於 ADAS 與資訊娛樂系統
此車用離電池處理器電源參考設計提供多功能受保護的電源樹狀架構,可為常見的 ADAS 與資訊娛樂處理器 (如 TDA4x-Q1、AM6x-Q1) 供電。上述處理器可搭配感測融合系統、攝影機模組及域控制器運作。詳細設計指南協助工程師建立受保護的電源系統。提供額外電源軌以支援 DDR 記憶體與輔助負載。設計內建 MSPM0 微控制器 (MCU),可用於設定電源軌電壓與時序。
參考設計
適用於備用電源的無縫切換參考設計

TIDA-01638 參考設計展現含備援電源的電源多工器。如果一個電源出現故障,系統需要切換至備用電源,並為下游負載提供不間斷的電源。因此,電源備援可確保其中一個電源供應發生故障時,系統可自動切換至另一個電源軌,以防止資料損失。
