Hello Jing,

Is this answer regarding SNS is still valid? I just wonder the answer is 3years old and wish to clarify again.

If I used D4 as below, do you expect any problem?

Do I have to disconnect the net on Green box below?

    Hi Vincent,

    it all depends on what you want to achieve here. Please refer to block diagram in Datasheet Page 15 for your specific application needs. in order to separate SNS from BAT, it's better to disconnect at green box. Also make sure your system is ok to be directly connected to battery.

    Best Regards,
