Hello , I'm using the BQ40Z50-R1 do the current sense , the circuit is like below （R19 is two 5 mΩ resistor parallel connect) . the return current have 5~6 mA offset , but is different in charging and discharging, for example , 2A charging return current value is 2005mA, but 2 A discharging return value is 1995mA , I checked the Rsense resistor was no problem , and also removed the Common-mode capacitance C19 and C20 , the problem still exist , apart from the offset voltage from layout , is there any other reason may cause this problem ? thanks !
