Abstract
A battery charging circuit includes a power management IC, a controller, and a feedback circuit. The power management IC is configured to manage the power charging to a battery. The controller is configured to provide a preset value of current and a preset value of voltage. The feedback circuit is coupled to the power management IC and the controller and the battery. The feedback circuit compares the preset value of current with a charging current to the battery, and compares the preset value of voltage with a charging voltage to the battery to obtain results of comparison, and provides a feedback signal to the power management IC according to the comparisons. The power management IC decreases or increases power output upon the comparisons.
