DATA SHEET

描述 / Descriptions

BRCL4054ME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BRCL4054ME成为便携式应用的理想选择。BRCL4054ME可以适合USB电源和适

配器电源工作。

The BRCL4054ME is a complete constant-current/constant voltage linear charger for single cell

lithium-ion batteries. Its ThinSOT package and low external component count make the

BRCL4054ME ideally suited for portable applications. Furthermore, the BRCL4054ME is specifically

designed to work within USB power specifications.

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。充电电压固定

于4.2V，而充电电流可通过一个电阻器进行外部设置当充电电流在达到最终浮充电压之后降至设定值

1/10时，BRCL4054ME将自动终止充电循环。

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 BRCL4054ME automatically

terminates the charge cycle when the charge current drops to 1/10th the programmed value after the

final float voltage is reached.

当输入电压（交流适配器或USB电源）被拿掉时，BRCL4054ME自动进入一个低电流状态，将电池

漏电流降至2uA以下。也可将BRCL4054ME置于停机模式，以而将供电电流降至25uA。

BRCL4054ME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。

When the input supply (wall adapter or USB supply) is removed, the BRCL4054ME automatically

enters a low current state, dropping the battery drain current to less than 2μA. The BRCL4054ME can

be put into shutdown mode, reducing the supply current to 25μA. 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.
