BQ25896: BQ25896 termintaion current current accuracy question

Part Number:BQ25896

Dear TI member

My custmoer set BQ25896 termination current to 128mA and Charge done voltage to 4.352V.

For now their termination current measurement arround 165mA~175mA for every board.

If we calculate the accuracy, 165/128=+28%, 175/128=+36%, the value seems larger then datasheet 256mA termination current +/-20% range.

I had check their test method, it seems OK and other project also use this method to test and had no this issue.

And I also check their reg setting, they don't use IRCOMP function, so I have no idea where is the root cause for this.

Please help check the 128mA termination current accuracy range should be around what range.

Or give me some advice where to check their system.

Thank you
