  "textContent": "A power supply system includes a regulator, outputting a system voltage; a load, receiving the system voltage to operate; a battery, charged by the system voltage; a charging transistor, receiving the system voltage and controlling a charging current to the battery; and a three-input amplifier, in which three factors including a charging current detection value, a reference charging current, and a reference limit current determined according to a difference between the system voltage and a minimum system voltage are input, and which obtains an output corresponding to a difference between the reference charging current and the charging current detection value when the reference charging current is equal to or less than the reference limit current, and obtains an output corresponding to a difference between the reference limit current and the charging current detection value when the reference charging current exceeds the reference limit current.",
