摘要： In a battery pack, an overcharge detecting circuit compares a voltage between a positive electrode and a negative electrode of a secondary battery with a threshold voltage to detect an overcharge of the secondary battery, and turns off a switching element. A series circuit including a thermistor and a resistor is arranged near the secondary battery and connected in parallel to the secondary battery. A comparator compares a voltage at a junction point of the thermistor and the resistor with a reference voltage corresponding to a predetermined temperature. In response to an output signal of the comparator, a changing unit changes the threshold voltage to a first value when a temperature of the secondary battery is below the predetermined temperature, and changes the threshold voltage to a second smaller value when the temperature of the secondary battery is above the predetermined temperature.

摘要： A first device: determines whether or not a terminal voltage at a terminal, where a temperature sensor, in which a physical quantity such as a resistance value or a voltage value varies due to changes in temperature, is connected, is in a first voltage range; controls the terminal voltage to vary in accordance with changes of the physical quantity, within the first voltage range, when the terminal voltage is determined to be in the first voltage range, and stops controlling the terminal voltage to vary within the first voltage range when the terminal voltage is determined not to be in the first voltage range; and detects temperature based on the terminal voltage. A second device: controls the terminal voltage to vary in accordance with changes of the physical quantity, within a second voltage range, which is different from the first voltage range; and detects temperature based on the terminal voltage.

摘要： A secondary protection IC is connected in parallel with a rechargeable battery and controls the charge and discharge of the rechargeable battery separately from a primary protection IC. The secondary protection IC includes a detection circuit that detects an overcharge or overdischarge of the rechargeable battery, a regulator that stabilizes the voltage of the rechargeable battery and outputs the stabilized voltage to the outside of the rechargeable battery, and a control terminal that controls the regulator with a control signal. Each of the detection circuit and the regulator performs a normal operation or stops operating based on the voltage of the rechargeable battery and the control signal.

摘要： A secondary battery protection integrated circuit includes a first power supply terminal, a second power supply terminal, an input terminal, an output terminal, and a control circuit. The control circuit turns a discharge control transistor off to change to a discharge-blocked state in which the output terminal and the first power supply terminal are coupled to each other, upon occurrence in a condition in which a potential level of the input terminal changes from a first level. The control circuit turns the discharge control transistor on in the discharge blocked state, upon occurrence of a condition in which the input terminal changes from a second level that is different from the first level.

摘要： A secondary-battery protection circuit is configured to, in response to detecting that a first switching circuit is turned on and a second switching circuit is turned on, supply a first output voltage to a first load between a first terminal and a second terminal; and supply a third output voltage to a second load between the first terminal and a third terminal, the third output voltage indicating the sum of the first output voltage and a second output voltage, the second output voltage corresponding to a voltage across a second secondary battery. In response to detecting that the first switching circuit is turned off and the second switching circuit is turned on, the secondary-battery protection circuit is configured to stop supplying the first output voltage to the first load; and stop supplying the third output voltage via the first terminal and the third terminal.
