AAT3681AIJS-4.2-3-T1 电池管理电源IC 4.5V~7V SO70JW-8 marking/标记 XIR USB端口/AC适配器锂离子电池充电器
| 功能Function | 充电管理 Charge Management |
| 电池化学Battery Chemistry | 锂离子 Lithium-Ion |
| 电压 - 电源Voltage - Supply | 4.5V~7V |
| Description & Applications | 500mA USB Port or AC Adapter Lithium-Ion/Polymer Battery Charger From a DC power source or USB port up to an input voltage of 7.5V. It requires just one external component. When charged from an AC adapter or USB port, the battery charging current can be set by an external resistor up to 500mA. In the event of an over-voltage, short-circuit, or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge. A status monitor output pin is provided to indicate the battery charge status by directly driving an external LED.Applications： Bluetooth Headsets DECT Headsets Digital Still Cameras MP3, Portable Music, and Portable Media Players Personal Data Assistants (PDAs) Wrist Watches Other Lithium-Ion/Polymer Battery-Powered Devices |
| 描述与应用 | 500mA的USB端口或AC适配器锂离子电池充电器 从输入的直流电源或USB端口电压为7.5V。它只需要一个外部元件，从AC适配器或USB端口，电池充电时，充电电流可通过外部电阻设置高达500mA。在过电压，短路的情况下， 或过温故障，设备将自动关闭，从而保护充电设备，控制系统和充电状态下电池。 A状态监视器输出引脚通过直接驱动外部LED的充电状态来指示电池。应用范围： 蓝牙耳机 DECT耳机 数码相机 MP3，便携式音乐和便携式媒体播放器 个人数据助理（PDA） 手表 其他锂离子电池供电设备 |
