DATA SHEET  
描述 / Descriptions  
BRCL4054BME是一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器。其SOT封装与较少  
的外部元件数目使得BRCL4054BME成为便携式应用的理想选择BRCL4054BME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  
离二极管反馈可对充电电流进行调节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。  
充电电压固定于4.2V充电电流可通过一个电阻器进行外部设置充电电流在达到最终浮充电压之  
后降至设定值1/10BRCL4054BME将自动终止充电循环BRCL4054BME的其他特点包括充电电流  
监控器、欠压闭锁、自动再充电和一个用于指示充电结束和输入电压接入的状态引脚。  
The BRCL4054BME is a complete constant-current/constant voltage linear charger for single cell  
lithium-ion batteries. Its Thin SOT package and low external component count make the  
BRCL4054BME ideally suited for portable applications. Furthermore, the BRCL4054BME 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. 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 BRCL4054BME automatically terminates the charge cycle when  
the charge current drops to 1/10th the programmed value after the final float voltage is reached.Other  
features include charge current monitor, under voltage lockout, automatic recharge and a status pin to  
indicate charge termination and the presence of an input voltage.
