S-82N1B屬于集成電路（IC）的電池管理。由艾普凌科有限公司制造生產(chǎn)的S-82N1B電池管理電池管理 PMIC（電源管理集成電路）系列產(chǎn)品可用于電池相關(guān)的監(jiān)測和控制功能，包括身份驗證、電池平衡、狀態(tài)監(jiān)測、電量計量、電源選擇、短路保護、過壓和欠壓保護等等。請注意，雖然該系列中的某些產(chǎn)品可能包括電池充電功能，但將充電功能作為主要功能的產(chǎn)品是單獨分類的。

The S-82N1B Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy

voltage detection circuits and delay circuits. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery

packs from overcharge, overdischarge, and overcurrent.

The S-82N1B Series has an input pin for power-saving signal (PS pin), allowing for reduction of current consumption by using

an external signal to start the power-saving function.
