  "textContent": "A charge and discharge control circuit controls charge and discharge of a secondary battery connected between a positive electrode power supply terminal and a negative electrode power supply terminal by using a discharge control switching element and a charge control switching element connected between the secondary battery and a load or a charger and includes a charger connection detector circuit that generates a charger connection detection signal, based on a voltage of an external negative electrode terminal connected to the charger; and a pull-up detector circuit that detects a pull-up of the voltage of the external negative electrode terminal, based on the voltage of the external negative electrode terminal, and generates a pull-up detection signal. The charge and discharge control circuit turns off the discharge control switching element, and then, turns on the same after receiving the pull-up detection signal and the charger connection detection signal.",
