About FD set issue. (BQ28400)

Dear. All.

I have one issue about FD(Fully discharged) set issue.

i using BQ28400 with Li-polymer 7.4V 12.5Ah.

Parameter for FD.

1. Configuration (Subclass 146)

   Full Discharge Set % (Offset 2) : 2%

   Full Discharge Clear % (Offset 3) : 5%

I tested 0.2C(2.5A) discharge.

When RSOC is 2%, FD didn't set.

When RSOC is 0%, FD didn't set.

When TDA is set, FD is set.

I cannot found FD set point.

Please help me.

Thank you.
