摘要： A multi charging current control circuit including a voltage reference unit, a current limiting unit, a current detector and a current control unit is provided. The voltage reference unit provides many reference voltages. The current limiting unit selects a corresponding reference voltage from the reference voltages according to a charge mode signal and outputs a control signal according to the corresponding reference voltage. The current detector detects a first and a second charging current. The current control unit controls the first charging current and the second charging current according to the control signal. The current detector feedbacks the first charging current and the second charging current detected to the current control unit, such that the current control unit adjusts the first charging current or the second charging current to make the sum of the first charging current and the second charging current less than or equal to a constant value.
