LM5066I provides robust protection and precision monitoring for 10- to 80-V systems. Programmable UV, OV, ILIMIT, and fast-short circuit protection allow for customized protection for any application. Programmable FET SOA protection sets the maximum power the FET is allowed to dissipate under any condition. The programmable fault timer (tFAULT) is set to avoid nuisance trips, ensure start-up, and limit the duration of over load events.

In addition to circuit protection, the LM5066I supplies real-time power, voltage, current, temperature, and fault data to the system management host through the I2C / SMBus interface. PMBus compliant command structure makes it easy to program the device. Precision telemetry enables intelligent power management functions such as efficiency optimization and early fault detection. LM5066I also supports advanced features such as I/V/P averaging and peak power measurment to improve system diagnostics.

LM5066I is pin-to-pin compatible with the LM5066 and offers improved telemetry accuracy and supports the Read_Ein command to monitor energy. See for a detailed comparison.

參考設計

PMP23496 — 適用於 48V 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。
