    • A charge protection circuit with a timing function is disclosed. The circuit includes a charge protection module constituting of a second switch, a second capacitor and a control integrated circuit (IC). The second switch Q2 is switched to turn on or turn off to charge or discharge the lithium-ion battery. The second capacitor configured for setting a delay time of a Ct terminal of the control IC, thus to prevent the battery from being overcharged. The circuit further includes a charge timing circuit configured for predetermining a time threshold value. When the charge time reaches the time threshold value, the charge timing circuit outputs a second high level signal to charge the second capacitor. The second capacitor triggers the control IC to turn off the second switch, thereby terminating the charge of the battery body.
    • 公开了具有定时功能的充电保护电路。 电路包括构成第二开关的电荷保护模块,第二电容器和控制集成电路(IC)。 第二开关Q2被切换以导通或关闭以对锂离子电池充电或放电。 第二电容器被配置为设置控制IC的Ct端子的延迟时间,从而防止电池过充电。 电路还包括配置用于预先确定时间阈值的充电定时电路。 当充电时间达到时间阈值时,充电定时电路输出第二高电平信号以对第二电容器充电。 第二电容器触发控制IC关闭第二开关,从而终止电池体的充电。
