关于二级保护

各位TI的大神，BQ3050开启二级保护的方法是怎样的啊？

是给相应的time位设置时间就可以了吗？另外Permanent Fail Cfg位需要设置吗？

[Voltage(2nd Level Safety)]
LT SOV Threshold = 4500
ST SOV Threshold = 4600
HT SOV Threshold = 4500
SOV Time = 0  //disable
PF SOV Fuse Blow Delay = 0
Cell Imbalance Current = 5
Cell Imbalance Fail Voltage = 1000
Cell Imbalance Time = 0//disable

谢谢各位！！

    是的，把相应的delay时间设成0会disable相应的二级保护。

     Permanent Fail Cfg是用来配置该PF是否需要在FUSE pin输出高电平。

    The Permanent Fail Cfg register enables or disables the use of the FUSE pin when the corresponding
    permanent fail error occurs
