METHOD AND SYSTEM USING A BATTERY VOLTAGE LOOP UNDER HIGH-CURRENT CONDITIONS

Systems and methods for using a battery voltage loop under high-current conditions are described. A method for operating a charger, the method includes setting, by a charger controller, a battery voltage threshold; setting, by the charger controller, an on-the-go (OTG) voltage threshold; computing, by a first comparator, a battery voltage error based on a difference between a battery voltage and the battery voltage threshold; computing, by a second comparator, an OTG voltage error based on a difference between an OTG voltage and the OTG voltage threshold; and selecting, by a loop selector, a battery voltage loop when the battery voltage error is smaller than the OTG voltage error.
