Charger and integrated circuit having first and second charging currents |
摘要 |
A charger of the present invention includes a charging transistor and a charging integrated circuit. The charging transistor is series-connected with a secondary battery to supply a charging current to the secondary battery. The charging integrated circuit is incorporated into a package having a higher heat releasability than that of the charging transistor. The charging integrated circuit controls the charging transistor and besides, supplies a charging current to the secondary battery. For this purpose, the charging integrated circuit includes a current source supplying this charging current. The charging current from the current source is supplied to the secondary battery together with the charging current from the charging transistor to charge the secondary battery.
