SMbus

SMbus(SystemManagementBus,系統管理總線)是1995年由Intel提出的,應用于移動PC和桌面PC系統中的低速率通訊。希望通過一條廉價并且功能強大的總線(由兩條線組成),來控制主板上的設備并收集相應的信息。

  • MSP430與bq電量計間采用SMbus通信接口的寬輸入電池充電器

    本應用報告描述了一個具有寬電壓輸入的智能電池充電器。其中的參考設計實現了在MSP430微控制器和兼容SMbus的電池電量計之間進行通信的系統管理總線(SMbus)協議。MSP430 器件通過SMbus 從電量計獲取電壓、電流和其它一些參數,之后通過調節輸出到dc/dc變換器模塊的PWM 占空比來傳遞電池所需的電量。
