Information equipment and battery charge circuit

Information equipment equipped with a DC power supply, a battery storing electric power from the DC power supply, and an information processing circuit for processing information, the information equipment comprising:

• a charge circuit located between the DC power supply and the battery, for controlling an output voltage of the DC power supply and applying the controlled voltage to the battery;
• a battery protection circuit for interrupting a first power supply path connecting the battery and the charge circuit when an anomaly of the battery occurs;
• an input voltage detection circuit for detecting an input voltage which is input from the DC power supply to the charge circuit;
• and
• an interruption circuit for determining that an anomaly of the charge circuit has occurred, and interrupting a second power supply path connecting the first power supply path or the DC power supply and the charge circuit when the input voltage detected by the input voltage detection circuit fluctuates and indicates an abnormal value.
