OVERCURRENT PROTECTION CIRCUIT AND BATTERY MODULE INCLUDING THE SAME

The present disclosure is related to an overcurrent protection circuit (100). An overcurrent protection circuit (100) includes an overcurrent protection unit (100A) to which a current measured by a current sensor (20) connected to a power source is input, and configured to increase an input voltage value (Vi) according to an input of the current over time, step-up the input voltage value (Vi) within a predetermined range in response to the input voltage value (Vi) exceeding a reference voltage value (Vref), and output an output voltage value (Vo) at a first level, and an output unit (150) connected to the overcurrent protection unit (100A) and configured to transmit the output voltage value (Vo) to a switch (30, 30A, 30B, 30C) connected between the power source and a load (60A, 60B, 60C).
