PROBLEM TO BE SOLVED: To provide a charging control circuit, capable of minimizing the heat loss due to a charging control transistor and further reducing the heat loss, without reducing the charging current. SOLUTION: The charging control circuit 6 is used to charge a battery 5 from a power supply terminal 1. The charging control circuit 6 is provided between a power supply and the charging control transistor 3 with a constant- voltage circuit 9. COPYRIGHT: (C)2003,JPO
