EUP8010X-1A高集成锂电池线性充电电源管理IC


EUP8010X-1A高集成锂电池线性充电电源管理IC DataSheet

概述
    EUP8010X系列是高集成锂离子(Li-Ion)和锂聚合物(Li-Pol)电池线性充电电源管理组件。         EUP8010X将功率FET,电流检测电阻,充电状态,反相电流保护集成于芯片中。在AC充电组态,利用外部电阻来设置充电电流大小,电流可高达1A。
    EUP8010X充电有三个区段,包含涓流充电,恒流与恒压充电。充电结束有两种控制方式:最小电流充电终止以及内部计数器计数充电终止。假如电池电压下降至再充电门限值以下,EUP8010X自动重新开始充电。当供应电源移除后,EUP8010X自动进入休眠模式。充电时无须外接MOSFET、电流检测电阻和隔离二极管。

特点
•  集成功率FET和电流感测,由AC配适器提供产生达约1A的充电电流
•  最小电流与安全时间充电终止
•  电池端反向逆漏电流保护
•  输出至LED或系统接口指示状态:充电或不正常工作
•  充电前和充电过程电池温度检测
•  含安全时间计数的预充电状态
•  低功耗自动休眠模式
•  3mm x 3mm TDFN-10封装
•  符合RoHS规范及Pb-Free
 
应用
•  智能电话
•  数码相机
•  PDA/MP3播放器
•  独立充电器

EUP8010X-Linear Li-Ion/Polymer Charger IC with Integrated FET and Charger Timer 

Description
The EUP8010X series are highly integrated single cell Li-Ion/Polymer battery charger IC designed for handheld devices. The EUP8010X integrates internal power FET, current sensor, charge status and reverse current protection in a single monolithic devices.When AC-adapter is applied, an external resistor sets the magnitude of the charge current, which may be programmed up to 1A.
The EUP8010X charges the battery in three phases: conditioning, constant current, and constant voltage. Charge is terminated based on minimum current. An internal charge timer provides a backup safety for charge termination. The EUP8010X automatically re-starts the charge if the battery voltage falls below an internal threshold. The EUP8010X also automatically enters sleep mode when DC supplies are removed. No external sense resistor or blocking diode is required for charging.

Feature
• Integrated Power FET and Current Sensor for Up to 1A Charge Applications
• Charge Termination by Minimum Current and Time
• Precharge Conditioning With Safety Timer
• Reverse Leakage Protection Prevents Battery Drainage
• Status Outputs for LED or System Interface Indicates Charge and Fault Conditions
• Optional Battery Temperature Monitoring Before and During Charge
• Automatic Sleep Mode for Low-Power Consumption
• Available in 3mm x 3mm TDFN-10 Package
• RoHS Compliant and 100% Lead (Pb)-Free

Application
• Smartphones
• Digital Cameras
• PDAs/ MP3 Players
• Stand-Alone Chargers
