DS2740依舊在生產(chǎn)中，假如您正準備開發(fā)新產(chǎn)品，我們推薦ModelGauge m5 MAX17211電量計。\n\n DS2740非常適合于為成本敏感的應用提供高精度電流通過量數(shù)據(jù)，以便于電池容量的監(jiān)視。電流采用雙向測量，動態(tài)范圍高達15位(DS2740U)或13位(DS2740BU)，凈流量在單獨的16位寄存器中進行累積。通過1-Wire?接口，DS2740允許主系統(tǒng)對其狀態(tài)和電流測量寄存器進行讀/寫訪問。每個器件具有唯一的工廠編程的64位網(wǎng)絡地址，允許主系統(tǒng)單獨尋址，支持多電池槽協(xié)同工作。接口可工作于標準或過驅(qū)動定時模式。\n\n 雖然DS2740主要設計用于主系統(tǒng)中，它同樣也可用于電池組中。利用DS2740和FuelPack?算法，再加上主機支持的溫度和電壓測量，就構成了一個完整而且精確的、用于估計剩余容量的方案。\n\n \n\n
