DS2745

低成本I2C電池監(jiān)測器; ? 16位雙向電流測量\n? 1.56μV LSB、±51.2mV動態(tài)范圍\n? 104μA LSB，±3.4A動態(tài)范圍(RSNS = 15mΩ)\n\n\n? 電流累計寄存器分辨率\n? 6.25μVhr LSB，±204.8mVh范圍\n? 0.417mAhr LSB，±13.65Ah范圍(RSNS = 15mΩ)\n\n\n? 11位電壓測量\n? 4.88mV LSB，0V至5V輸入范圍\n? 11位溫度測量\n? 0.125°C分辨率，-20°C至+70°C\n? 工業(yè)標(biāo)準(zhǔn)I2C接口\n? 低功耗；\n? 工作電流：70μA典型值, 100μA最大值\n? 休眠電流：1μA典型值，3μA最大值;

DS2745依舊在生產(chǎn)中，假如您正準(zhǔn)備開發(fā)新產(chǎn)品，我們推薦ModelGauge m5 MAX17055電量計。\n\n DS2745提供電流、電壓以及溫度測量數(shù)據(jù)，用于監(jiān)視電池容量，非常適合成本敏感產(chǎn)品。具體應(yīng)用中，DS2745既可安裝在主機(jī)側(cè)，也可安裝在電池包側(cè)。DS2745通過監(jiān)視外部檢測電阻兩端的壓降實現(xiàn)電流的測量和庫侖計數(shù)，通過一個專用的電壓檢測輸入完成電壓測量，溫度測量則在芯片內(nèi)部完成。具有軟件可編程地址的標(biāo)準(zhǔn)I2C接口，微處理器可通過它訪問DS2745內(nèi)部所有數(shù)據(jù)和狀態(tài)寄存器。不使用電池包時，低功耗休眠模式可以節(jié)省電能。\n\n \n\n
