Abstract

一种充电电路(10)与电子装置(100)，充电电路(10)包括第一接口(11)、电源单元(13)、充电管理单元(12)、控制单元(14)、第一开关单元(15)以及保护单元(17)，控制单元(14)用于控制第一充电电流(I1)经由充电管理芯片转换为第二充电电流(I2)并为电源单元(13)充电执行普通充电，或者控制第一充电电流(I1)经由第一开关单元(15)直接提供至电源单元(13)执行快速充电。保护单元(17)电性连接第一开关单元(15)与控制单元(14)，当第一充电电流(I1)经由所述第一开关单元(15)直接提供至电源单元(13)时，若第一充电电压(V1)大于阈值且控制单元(14)死机，保护单元(17)输出第一保护信号至第一开关单元(15)以控制第一开关单元(15)停止将所述第一充电电流(I1)提供至所述电源单元(13)，并使得电源单元(13)停止充电从而防止过大的第一充电电压(V1)损坏电源单元(13)。
