摘要： A circuit for charging a battery pack includes a power converter and a charger controller. The power converter is operable for receiving an input power, and for providing a charging power for charging the battery pack. The power converter provides galvanic isolation between input circuitry and output circuitry of the circuit. The input circuitry shares a first ground potential with the input power, and the output circuitry shares a second ground potential with the charging power. The charger controller in the input circuitry includes a modulator for generating a driving signal to drive the power converter and control the charging power.

摘要： 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.

摘要： A circuit for charging a battery pack includes a transformer and a charger controller. The transformer is operable for receiving an input power and for providing a charging power according to a driving signal to charge the battery pack. The charger controller is operable for monitoring a status of the battery pack, for selecting a charging mode from multiple charging modes according to the status, and for generating the driving signal according to the charging mode to adjust the charging power. The charger controller further executes a state machine that stores data indicating predetermined battery statuses that cause saturation of the transformer, and that selects a protection mode in which said charging power is restricted if the status of the battery pack matches to one of the predetermined battery statuses.
