Abstract
A battery protection IC applied to a battery charging system is provided, where the battery charging system includes a charger and a switch, the switch is coupled between the charger and a battery when the battery is put into the battery charging system, and the battery protection IC includes a voltage divider, a comparator and a controller. The voltage divider is coupled to a first node of the switch, and is utilized for dividing a voltage of the first node to generate a divided voltage, whereat least one resistor of the voltage divider is formed by two different types of fuses. The comparator is utilized for comparing the voltage with a reference voltage to generate a comparison result. The controller is utilized for generating a control signal according to the comparison result, where the control signal is utilized for switching on or switching off the switch.
