XC3062 采用SOT23-6封装，是一款完整的单节锂电池充电器，自带OVP=6.8V,VIN输入耐压30V ,BAT耐兼容大小500-600mA充电电流，采用涓流，恒流，恒压控制，SOT23-6封装与较少的外部元件数目使得XC3062成为便携式应用的理想选择。XC3062可以适合USB电源和适配器电源工作。
XC3062采用了内部PMOSFET架构，加上防倒充电路，所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行自动调节，以便在大功率操作或高环境温度条件下对芯片温度加以限制。充满电压4.2V，充电电流可通过一个电阻器进行外部设置。当电池达到预设电压后，充电电流将至设定值1/10，芯片将自动终止充电。
当输入电压（交流适配器或者USB电源）被拿掉时，XC3062自动进入一个低电流状态，电流漏电流在1uA以下，XC3062的其他特点包括欠压闭锁，自动再充电以及两个用于指示充电状态的引脚。
GENERAL DESCRIPTION
The XC3062 Series is a complete constant
current & constant voltage linear charger for
single cell lithium-ion batteries. Its SOT23-6L
package and low external component counts
make the XC3062 Series ideally suited for
portable applications. Furthermore, the XC3062
Series is specifically designed to work within USB
power specifications.
No external sense resistor is needed, and no
blocking diode is required due to the internal
MOSFET architecture. The charge voltage is fixed
at 4.2V/4.3V/4.35V/4.4V, and the charge current
can be programmed externally with a single
resistor. The XC3062 Series automatically
terminates the charge cycle when the charge
current drops to 1/10 the programmed value after
the final float voltage is reached.
When the input supply (wall adapter or USB
supply) is removed, the XC3062 Series
automatically enters a low current state, dropping
the battery current to less than 2.5uA. The Under
voltage lockout, automatic recharge and two
status pins to indicate charge and charge
termination.
