When the power supply is connected and the battery is not full, the power supply starts to charge the battery normally through the control of cxch7680 cxch7680c

When the power supply is connected and the battery is not full, the power supply starts to charge the battery normally through the control of cxch7680 cxch7680c (as mentioned above, at this time, no matter what polarity the battery is connected to the circuit, it can charge normally). The typical charging current is about 130 MA / cob; At 250mA / dip-8, the voltage at both ends of the battery rises slowly. When the voltage of battery 5 rises to 4.25v (typical value), the charging process is over and the battery is saturated. The status of L2 in this process is described in the function status table

Product introduction

   产品概述 返回TOP2Fs嘉泰姆


1、正常充电及饱和检测

  电源连通并且接入未满电池时,电源开始通过CXCH7680  CXCH7680C的控制对电池进行正常充电(如前所述,此时不论电池以何种极性接入电路,均能正常充电),充电电流典型值约为 130 毫安/COB; 250 毫安/DIP-8,电池两端电压缓缓升高,当电池5电压升高到 4.25V(典型值)时6,充电过程结束,电池已饱和。此过程中 L2 的状态参见功能状态表的描述。2Fs嘉泰姆

2、短路保护2Fs嘉泰姆

  若在电源接入后发生电池短路的情况,则 CXCH7680  CXCH7680C内部“短路保护”系统会自动将充电回路切断,避免产生大电流。此时 L1、L2 状态参见功能状态表的描述。2Fs嘉泰姆

3、生产线特殊极性换转测试2Fs嘉泰姆

   成品之生产线在测试极性转换时通常是以不断 VDD 电源的情况下直接快速作电池极性转换并且立即充电,忽略了电池极性识别过程,为此要求在作极性转换测试时,拨转换开关的速度要慢些,应断开充电电流约 0.8 秒以上使芯片有一定的回滞时间,即停充电约 0.8 秒再转向另一边,这样才比较安全。QC 在作来料检测时务必在断电后再取放 IC。2Fs嘉泰姆
