Abstract
A charging circuit can include: a linear regulator configured to receive an external input source; a charge pump coupled between the linear regulator and a charging terminal, where the charging terminal is coupled to a battery; and a control circuit configured to generate a first control signal according to a current sampling signal representing a charging current of the battery and a voltage sampling signal representing a charging voltage of the battery, in order to control the linear regulator, such that at least one of the charging current and the charging voltage meet charging requirements.
