An integrated circuit for protecting a secondary battery may include: a power-supply terminal connectable with a positive terminal of the secondary battery; a ground terminal connectable with a negative terminal of the secondary battery; and a control circuit for controlling a discharge-stop circuit to stop discharging the secondary battery. In response to a power-supply voltage between the power-supply terminal and the ground terminal being at or above a first threshold voltage, which is higher than a second threshold voltage, the control circuit carries out a first operation. When a first condition in which the power-supply voltage is lower than the first threshold voltage lasts a first period of time, the control circuit starts the discharge-stop circuit. When a second condition in which the power-supply voltage is lower than the second threshold voltage lasts a second period of time, shorter than the first period, the control circuit starts the discharge-stop circuit.
