PROTECTIVE MONITORING CIRCUIT AND BATTERY PACK |
摘要 |
A protective monitoring circuit includes a protective circuit to detect at least one of overcharging, overdischarging, and overcurrent of a chargeable secondary battery to control whether to turn on or off a control transistor to protect the secondary battery, and a secondary-battery monitoring circuit, having a reduced size and having a breakdown voltage lower than a battery voltage of the secondary battery, to detect a status of the secondary battery, wherein the protective circuit generates a voltage that is commensurate with an output voltage of the secondary battery and that is within a predetermined tolerance voltage range of the secondary-battery monitoring circuit, and the secondary-battery monitoring circuit generates a detection value responsive to the generated voltage supplied from the protective circuit, the detection value being indicative of the output voltage of the secondary battery. |

1. A protective monitoring circuit, comprising:
a protective circuit to detect at least one of overcharging, overdischarging, and overcurrent of a chargeable secondary battery to control whether to turn on or off a control transistor to protect the secondary battery; and a secondary-battery monitoring circuit to detect a status of the secondary battery, wherein the protective circuit generates a voltage that is commensurate with an output voltage of the secondary battery and that is within a predetermined tolerance voltage range of the secondary-battery monitoring circuit, and the secondary-battery monitoring circuit generates a detection value responsive to the generated voltage supplied from the protective circuit, the detection value being indicative of the output voltage of the secondary battery. |
