Dear sir / madam,

I want to make a mobile charger which should also read the battery level. Please suggest me appropriate the component.

    Manoj,

    What is your battery capacity, and therefore charge current, and power source for the charger? There are only a few chargers with an integrated ADC that reports battery level in I2C registers. The bq25120A family is for small batteries requiring lower charge currents. The bq25896 is for larger batteries requiring higher current currents. For very accurate battery level information, most customers use a fuel gauge IC in addition to battery charger.
