CHARGER DRIVING CIRCUIT, INTEGRATED CIRCUIT, CHARGER, CHARGING CONTROL METHOD, AND CHARGING CONTROL SYSTEM

摘要

Disclosed are a charger driving circuit (100), an integrated circuit (400), a charger (20), a charging control method, and a charging control system (40). The charger driving circuit comprises an isolated power supply module (110), a control switch (130), and a charging channel switch (140). The isolated power supply module has a power supply input end (Vin) and a power supply output end (Vout), and comprises a charge pump circuit (111), wherein the power supply input end is connected to the power supply output end by means of the charge pump circuit, and the power supply input end is connected to a voltage source (VCC). The control switch is electrically connected to the power supply output end. The charging channel switch is used for connecting the control switch and a charging battery (70), and the charging channel switch is used for being turned on and turned off under the control of the control switch, so as to control whether to charge the charging battery. The charger utilizes the charge pump circuit to form the isolated power supply module, such that the cost of purchasing an isolated power supply is avoided, the volume of the charger is small and the structure thereof is simple, and same is suitable for driving a high-end MOS transistor.
