IC One Cell Lithium-ion/Polymer Battery Protection IC FHI01 DESCRIPTION FEATURES 概述及特點 The FHI01 series battery protection IC is designed to FHI01 系列產品用於可反復充電的單個鋰離子電池 protect lithium-ion/polymer battery from damage or 或聚合物鋰電池的保護電路中，它不僅控制鋰電池 degrading the lifetime due to overcharge 、 正常使用，又能有效地保護鋰電池免受過充電、過 over-discharge and/or over-current for one-cell 放電、過電流的不正常使用。 lithium-ion/polymer battery powered systems ,such as 晶片採用小封裝和較少的週邊電路元件，使它能理 cellular phones 想地集成到手機電池板有限的空間裏。精度±50mV The ultra-small package and less required external components make it ideal to integrate the FHI01 in to 過充電檢測電壓保證了電路安全、充分的充放電利 the limited space of battery pack. The accurate±50mV 用。在待機狀態時，耗電較小。 overcharging detection voltage ensures safe and full utilization charging. The very low standby current drains little current from the cell while in storage. Miniature package SOT-23-6 微型封裝：SOT-23-6 Low Dissipation ： 低耗電：極低的靜態電流3.5µA Ultra-Low Quiescent Current at 3.5µA 極低的待機電流0.3µA Ultra-Low Power-Down Current at 0.3µA 高精度的檢測電壓閾值：4.3±50mV(TOP=25℃) Precision Overcharge Protection Voltage 4.3± 內置過流保護功能：0.1V～0.18V 50mV(TOP=25℃) for FHI01. 過充電輸出延時：當C2=0.01µ F 時,約為 120ms Load Detection Function during over-current mode ： 較少的週邊元件：兩個電阻，兩個電容 0.1V～0.18V Delay time are generated by external capacitor C2,when C2=0.01µ F, the delay time about 120ms. Less required external components ：Tow resistors and two capacitors. Applications 應用 Protection IC for one-cell Lithium-Ion/Lithium-Polymer 單節鋰離子電池中聚合物鋰電池保護系統 Battery Pack.
