Answer: When the charging current is higher than the charging overcurrent protection current and the duration reaches the charging overcurrent protection delay, the system enters the charging overcurrent protection state and turns off the charging MOS. When the charging  overcurrent protection occurs, the system will automatically release the charging overcurrent protection state after 1min. If the overcurrent protection occurs 10 times in a row, the system will automatically lock the state and will not automatically release it. Discharge is also possible.
