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.

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 battery pack has first through third external terminals connected to positive and negative power supply terminals and a voltage detection terminal, respectively. A secondary battery is connected between the first external terminal and the third external terminal. A protection circuit controls ON/OFF of first and second switching elements provided on a wiring between the secondary battery and a load or a charge device by detecting an overcharge, an overdischarge and an overcurrent of the secondary battery. A first thermistor is connected between the second external terminal and the third external terminal. A series circuit containing a second thermistor and a resistor is provided in parallel to the secondary battery. A third switching element is connected between the second external terminal and the third external terminal. The protection circuit turns on the third switching element and short-circuits between the second external terminal and the third external terminal when a detection is made by the second thermistor that a temperature of the secondary battery exceeds a predetermined temperature.

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 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.
