BQ24130: BQ24130 charging problem

Part Number: BQ24130

Dear all,

I met a problem when using BQ24130 in charging for a Super capacitor.The output charging current does not meet the current I set. For example,when CMOD is set to low,and Viset2=2V, the sense resistor is set to 100mΩ,the theoretical charge current should be 200mA, but the The actual measured value is only 160mA.Change  sense resistor to 50 mΩ,the theoretical charge current should be 400mA, but I only get 273mA fron the output!!! and the same problem occurs in the fast charge mode.could you give me some suggestion?
