BQ24773: BQ24773 IADP PIN and IBAT pin Voltage issue

Part Number:BQ24773

Hi，now my customer uses BQ24773 for charger，now above question need you help to check it，tks！

11pin：SDA 、12pin：SCL、 5pin：ACOK 、10pin：CH_PRO、 13pin：CHPIN、 14pin：CMPOUT； This 6PIN high level is 3.3V, but the 7pin：IADP and  8pin：IBAT  is be connected to the IO of MCU，however，the MCU's IO voltage is 1.8V，but the PIN and IBAT pin  output Voltage is clamped below 3.3 V , now we also recommend LSF0102 to design as 1.8V-3.3V，but in customer view，they want to use Voltage divider resistor to replace the LSF0102，could you help to check it whether is feasible
