| 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 | 4V~5.5V |
| Description & Applications | USB Port Lithium-Ion/Polymer Battery Charger The AAT3688 is a highly integrated single cell lithium-ion/polymer battery charger IC designed to operate with USB port inputs. An optional Charge Reduction Loop is built in to allow users to charge the battery with available current from a USB port, while keeping the port voltage regulated. In the event of an over-voltage or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge. Applications： Bluetooth Headsets Cellular Telephones Digital Still Cameras Hand-Held PCs MP3 Players Personal Data Assistants (PDAs) Other Lithium-Ion/Polymer Battery-Powered Devices |
| 描述与应用 | USB接口锂离子电池充电器 AAT3688是一个高度集成的单电池锂离子电池充电器IC设计与USB端口输入。是建立在允许用户可从USB端口给电池充电减少充电回路，同时保持端口电压调节。在过电压或过温故障的情况下，该设备将自动关闭，从而保护充电设备，控制系统，和充电状态下电池。应用范围： 蓝牙耳机 蜂窝电话 数码相机 手持式电脑 MP3播放器 个人数据助理（PDA） 其他锂离子电池供电设备 |
