LC709203F屬于集成電路（IC）的電池管理。由安森美半導(dǎo)體公司制造生產(chǎn)的LC709203F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(cè)和控制功能，包括身份驗(yàn)證、電池平衡、狀態(tài)監(jiān)測(cè)、電量計(jì)量、電源選擇、短路保護(hù)、過壓和欠壓保護(hù)等等。請(qǐng)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(dú)分類的。

Overview

LC709203F is a Fuel Gauge for a single lithium ion battery. It is part of our Smart LiB Gauge family of Fuel Gauges which measure the battery RSOC (Relative State Of Charge) using its unique algorithm called HG-CVR. The HG-CVR algorithm eliminates the use of a sense resistor and provides accurate RSOC information even under unstable conditions (e.g. changes of battery; temperature, loading, aging and self discharge). An accurate RSOC contributes to the operating time of portable devices.

LC709203F is available in two small packages realizing the industries smallest PCB footprint for the complete solution. It has minimal parameters to be set by the user enabling simple, quick setup and operation.
