MAX17043/MAX17044為結(jié)構(gòu)緊湊、低成本、主機側(cè)電量計，用于手持及便攜產(chǎn)品的鋰離子(Li+)電池的電量計量。MAX17043配置為單節(jié)鋰電池計量，MAX17044配置為兩節(jié)2S電池組計量。\n\n MAX17043/MAX17044采用成熟的Li+電池建模方案(稱為ModelGauge?)，在整個充/放電過程中連續(xù)跟蹤電池的相對充電狀態(tài)(SOC)。與傳統(tǒng)的電量計不同，ModelGauge算法省去了電池的再學(xué)習(xí)過程以及外部檢流電阻。器件提供溫度補償，使得μC與器件之間的交互操作降至最少。\n\n 快速啟動模式提供準(zhǔn)確的電池SOC初始估值。這一特性允許IC放置在系統(tǒng)側(cè)，降低成本和供電鏈路對電池的約束。通過I2C接口讀取電池容量的測量和估算數(shù)據(jù)。MAX17043/MAX17044采用0.4mm間隔的9焊球UCSP?封裝或2mm x 3mm、8引腳TDFN無鉛封裝。\n\n \n\n
