自动进入睡眠状态两个电源都被卸下时的模式CXLB7388高度集成的单电池手提式锂离子聚合物电池充电器设备集成功率场效应管和电流传感器从交流适配器到1A充电应用集成USB控制

CXLB7388系列是高度集成的单电池手提式锂离子/聚合物电池充电器设备。CXLB7388X接受两个电源输入，通常一个来自USB端口，另一个来自交流适配器。CXLB7388X自动选择
USB端口或交流适配器作为系统。在USB配置中，主机可以选择100毫安和500毫安的两种预设充电率。在交流适配器配置外部电阻器设置充电电流的大小，可以是编程为1A。CXLB7388X分三个阶段为蓄电池充电：调节、恒定电流和恒定电压。根据最小电流终止充电。一个内部充电计时器提供备用充电安全终止。CXLB7388X自动重新启动如果蓄电池电压低于内部电压，则充电门槛。CXLB7388X也会自动进入睡眠状态两个电源都被卸下时的模式。没有外感充电需要电阻器或阻塞二极管。CXLB7388X集成了内部功率FET、电流
传感器、充电状态和反向电流保护单片器件。

The CXLB7388X series are highly integrated single cell

Li-Ion/Polymer battery charger IC designed for handheld

devices. The CXLB7388X accepts two power inputs,

normally one from a USB port and another one from

AC-adaptor. The CXLB7388X automatically selects the

USB-Port or the AC-adapter as the power source for the

system. In the USB configuration, the host can select from

the two preset charge rates of 100 mA and 500 mA. In the

AC−adapter configuration an external resistor sets the

magnitude of the charge current, which may be

programmed up to 1A.

The CXLB7388X 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 CXLB7388X automatically re-starts the

charge if the battery voltage falls below an internal

threshold. The CXLB7388X also automatically enters sleep

mode when both supplies are removed. No external sense

resistor or blocking diode is required for charging.

The CXLB7388X integrates internal power FET , current

sensor, charge status and reverse current protection in a

single monolithic devices.
