摘要：A charge control device has a full charge detection circuit for checking whethera secondary cell is in a fully charged state or not based on the charge voltage and/or thecharge current of the secondary cell, a control circuit for controlling the feeding ofelectric power to the secondary cell according to the output of the full charge detectioncircuit, a storage circuit for storing control information, and a setting circuit for settingthe level of the charge voltage and/or the charge current at which the full chargedetection circuit recognizes the fully charged state according to the control informationread from the storage circuit. The control information is fed into the storage circuit fromoutside. With this configuration, it is possible to accurately control the charging of asecondary cell by canceling the influence of stress occurring when an IC is packaged ormounted on a circuit board and other factors.
