联益微最新推出高性能线性恒流充电芯片LY5056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。其底部带有散热片的SOP8封装与较少的外部元件数目使得LY5056成为便携式应用的理想选择。LY5056可以适合USB 电源5V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,LY5056将自动终止充电循环。
当输入电压(交流适配器或USB 电源)被拿掉时,LY5056自动进入一个低电流状态,将电池漏电流降至2uA以下。LY5056在有电源时也可置于停机模式,将供电电流降至50uA。
LY5056的其他特点包括电池温度检测、欠压闭锁、自动再充电和两个用于指示充电、结束的LED状态引脚。

TEMP(引脚1):电池温度检测输入端。将TEMP管脚接到电池的 NTC传感器的输出端。 如果TEMP管脚的电压小于输入电压45 %或者大于输入电压的80%,意味着电池温度过低或过高,则充电被暂停。如果TEMP 直接接GND,电池温度检测功能取消,其他充电功能正常。
PROG(引脚2 ):恒流充电电流设置和充电电流监测端。从PROG 管脚连接一个外部电阻到地端可以对充电电流进行编程。在预充电阶段,此管脚的电压被调制在0.1V;在恒流充电阶段,此管脚的电压被固定在 1V。在充电状态的所有模式,测量该管脚的电压都可以根据下面的公式来估算充电电流:
Vprog
Ibat=-----------*1200
Rprog
GND(引脚3 ):电源地。
Vcc (引脚4):输入电压正输入端。此管脚的电压为内部电路的工作电源。当Vcc与BAT 管脚的电压差小于30mV 时,LY5056将进入低功耗的停机模式,此时BAT 管脚的电流小于2uA
BAT(引脚 5 ):电池连接端。将电池的正端连接到此管脚。在芯片被禁止工作或者睡眠模式,BAT 管脚的漏电流小于2uA。BAT管脚向电池提供充电电流和 4.2V的限制电压.
STDBY(引6):电池充电完成指示端。当电池充电完成时STDBY被内部开关拉到低电平,表示充电完成。除此之外,管脚将处于高阻态。
CHRG(引脚引脚):漏极开路输出的充电状态指示端。当充电器向电池充电时,CHRG管脚被内部开关拉到低电平,表示充电正在进行;否则CHRG管脚处于高阻态.
CE(引脚8)芯片始能输入端。高输入电平。将使TP4056 处于正常工作状态;低输入电平使LY5056 处于被禁止充电状态。CE 管脚可以被TTL电平或者CMOS 电平驱动。
