DATA SHEET  
描述 / Descriptions  
BRCL4056BSE 一款完整的恒定电流/恒定电压线性控制单节锂离子电池充电器有电池正负极反接保护  
功能。其 ESOP-8 封装与较少的外部元件数目使得 BRCL4056BSE 成为便携式应用的理想选择。  
BRCL4056BSE 可以适合 USB 电源和适配器电源工作。  
由于采用了内部 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。充满电压固定于  
4.20V充电电流可通过一个电阻器进行外部设置电池达到 4.20V 之后电电流降至设定值 1/10,  
BRCL4056BSE 将自动终止充电。  
当输入电压(交流适配器或 USB 电源)被拿掉时,BRCL4056BSE 自动进入一个低电流状态,电池漏电流  
3uA 以下。BRCL4056BSE 的其他特点包括充电电流监控器、欠压闭锁、自动再充电和两个用于指示充  
电结束和输入电压接入的状态引脚。  
BRCL4056BSE is a complete CC/CV linear charger for single cell lithium-ion batteries,It has the function  
of positive and negative electrode protection for battery.Its ESOP-8 package and low external  
component count make the BRCL4056BSE ideally suited for portable applications. Furthermore, the  
BRCL4056BSE 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 P-MOSFET  
architecture. Thermal feedback regulates the charge current to limit the die temperature during high  
power operation or high ambient temperature .The charge voltage is fixed at 4.2V,and the charge current  
can be programmed externally with a single resistor. The BRCL4056BSE automatically terminates the  
charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage  
is reached.  
When the input supply (wall adapter or USB supply) is removed the BRCL4056BSE automatically enters  
a low current state dropping the battery drain current to less than 3μA. Other features include charge  
current monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and  
charge termination.
