您好，
我正在使用BQ25883芯片给7.4v双节锂电池充电。
使用BQ25883内部寄存器默认值，当插入可编程直流电源当做输入源（设置成5.2V@3A），电流大一下后（STAT灯闪一下后马上灭了），电流也马上没了，寄存器显示HIZ模式，
之后如果程序上将HIZ清空，它还会充一下电又不充了，又进入高阻模式。
VBUS输入电压5.2V,3A，电池6.5V，寄存器值如下：
[INFO]TaskCharge: REG00 = A0
[INFO]TaskCharge: REG01 = DE
[INFO]TaskCharge: REG02 = 84
[INFO]TaskCharge: REG03 = 39
[INFO]TaskCharge: REG04 = 22
[INFO]TaskCharge: REG05 = 9D
[INFO]TaskCharge: REG06 = 7D
[INFO]TaskCharge: REG07 = 02
[INFO]TaskCharge: REG08 = 0D
[INFO]TaskCharge: REG09 = F6
[INFO]TaskCharge: REG0A = 00
[INFO]TaskCharge: REG0B = 80
[INFO]TaskCharge: REG0C = 30
[INFO]TaskCharge: REG0D = 00
[INFO]TaskCharge: REG0E = 00
[INFO]TaskCharge: REG0F = 01
[INFO]TaskCharge: REG10 = 82
[INFO]TaskCharge: REG11 = 08
[INFO]TaskCharge: REG12 = 88
