Charge control circuit and method of adjusting voltage for detecting full charge of secondary battery in same

摘要

In a charge control circuit comprising a full charge detection voltage supply device supplying a predetermined full charge detection voltage for detecting a full charge status; and a comparator including a charge status voltage input unit to which is inputted a charge status voltage indicative of the charge status of a secondary battery and a full charge detection voltage input unit to which the full charge detection voltage is inputted, the comparator outputting a result of a comparison between the charge status voltage and the full charge detection voltage, the charge control circuit further comprises an external terminal connected to the full charge detection voltage input unit of the comparator and for adjusting the full charge detection voltage, with an electronic component for adjusting the full charge detection voltage being connectable to the external terminal.
