bq2461x是一款高度集成的鋰離子或鋰聚合物開關(guān)模式電池充電控制器。該器件提供恒定頻率同步開關(guān)PWM控制器,具有高精度充電電流和電壓調(diào)節(jié),充電預(yù)處理,終端,適配器電流調(diào)節(jié)和充電狀態(tài)監(jiān)控。
bq2461x分三個(gè)階段為電池充電:預(yù)充電,恒定電流和恒定電壓。
當(dāng)電流達(dá)到用戶可選的最低電平時(shí),充電終止。可編程充電定時(shí)器提供安全備份。如果電池電壓低于內(nèi)部閾值,bq2461x會(huì)自動(dòng)重啟充電周期,當(dāng)輸入電壓低于電池電壓時(shí),bq2461x會(huì)進(jìn)入低靜態(tài)電流休眠模式。
