Abstract
An electronic device includes a charging integrated circuit (IC) including a direct charging circuit that charges a battery; and an application processor that issues a request to an external power source to output a maximum voltage corresponding to a target current, performs a ramp-up operation on a charging current input to the charging IC on the basis of the maximum voltage, compensates for a difference between the charging current and the target current in response to the charging current entering a constant current period, and enters a sleep mode during the constant current period in response to that the charging current reaching the target current.
