數(shù)據(jù): bq27542-G1 用于電池組集成的單節(jié)鋰離子電池電量監(jiān)測(cè)計(jì) 數(shù)據(jù)表
德州儀器(TI)的bq27542-G1鋰離子電池電量監(jiān)測(cè)計(jì)是一款微控制器外設(shè),可為單節(jié)鋰離子電池組提供電量監(jiān)測(cè)。該器件可實(shí)現(xiàn)精確的電池電量監(jiān)測(cè),并且對(duì)系統(tǒng)微控制器固件開(kāi)發(fā)的要求極低。這款電量監(jiān)測(cè)計(jì)駐留在電池組內(nèi)或者內(nèi)置電池(不可拆卸)的系統(tǒng)主板上。此電量監(jiān)測(cè)計(jì)采用已獲專利溫度(°C)等信息。該器件還提供針對(duì)內(nèi)部短路或電池端子斷開(kāi)事件的檢測(cè)功能。
這款電量監(jiān)測(cè)計(jì)還特有針對(duì)安全電池組認(rèn)證(使用SHA-1 /HMAC認(rèn)證算法)的集成支持功能。
