A charging path includes a charging switch for transferring a charging current from an input terminal to an output terminal. The charging path further includes a first enable terminal coupled to the charging switch. The first enable terminal receives a first enable signal to control the charging switch to operate in either a first mode, a second mode, or a third mode, based on a status of the output terminal. More specifically, in the first mode, the charging switch is fully turned off. In the second mode, an equivalent resistance of the charging switch is determined by a control terminal of the charging switch. In the third mode, the charging switch is turned off. |
