Abstract

A battery protection circuit includes a voltage source, a first resistor, a charging controller, a first charging transistor, a second resistor, and a current voltage converter. The first resistor includes a first terminal connected to the voltage source. The charging controller supplies a charging control current through a charging control terminal. The first charging transistor includes a gate terminal and a first terminal. The second resistor is connected between the gate terminal and first terminal of the first charging transistor. The current voltage converter is connected to a second terminal of the first resistor to electrically connect the voltage source to the gate terminal of the first charging transistor depending on the charging control current.
