摘要： In a charge control circuit that adjusts a charging current flowing through a battery to be charged from a power supply, a sense resistor is provided on a charging path to the battery from an external power supply. A charging current adjustment circuit adjusts the charging current based on an error voltage between a voltage drop across the sense resistor and a predetermined reference voltage. The charging control circuit is integrated in a package. The charging current is inputted to a current input terminal. A battery terminal outputs the charging current to the battery. The current input terminal and the battery terminal also function as terminals used to measure a resistance value of the sense resistor. A voltage monitoring terminal is provided to measure the reference voltage in an inspection process.

摘要： A first error amplification circuit amplifies a difference between a predetermined reference voltage and a first detection voltage that corresponds to the output voltage of a DC/DC converter, so as to generate a second voltage. A voltage level judgment circuit generates a third voltage having a discrete level that corresponds to the amplitude of a first voltage. A multiplying/dividing circuit multiplies the first voltage by the second voltage, and divides the resulting product by the third voltage, so as to generate a fourth voltage. A comparator compares the fourth voltage with a second detection voltage that corresponds to a current that flows through a switching transistor included in the DC/DC comparator. A driving circuit turns on the switching transistor for each predetermined period, and turns off the switching transistor according to the output of the comparator every time the second detection voltage becomes higher than the fourth voltage.
