Mobile information processing device, integrated circuit, and battery pack

A mobile information processing device comprising:

• a secondary battery for storing electric power;
• a power feeding circuit configured to supply electric power to the secondary battery;
• a load circuit that includes an electronic circuit that is supplied with electric power from the secondary battery and a sensor that is controlled by the electronic circuit;
• a first current detection circuit configured to, when a first enable signal is in an activated state, detect a current flowing between a first node connected to one end of the secondary battery and a second node connected to the power feeding circuit or the load circuit, and generate an output signal, and when the first enable signal is in a deactivated state, stop a current detection operation;
• a first voltage detection circuit that is configured to detect a voltage at the first node, and generate an output signal;
• and
• a control circuit that is configured to generate the first enable signal and supply the first enable signal to the first current detection circuit, and is configured to fetch the output signal of the first voltage detection circuit after a first period has elapsed from when the first enable signal transitioned from a deactivated state to an activated state.

An integrated circuit comprising:

• a first current detection circuit that, when a first enable signal is in an activated state, detects a current flowing between a first node and a second node;
• and when the first enable signal is in a deactivated state, stops a current detection operation;
• a first voltage detection circuit that detects a voltage at the first node, and generates an output signal;
• and
• a control circuit that generates the first enable signal and supplies the first enable signal to the first current detection circuit, the control circuit being configured to not fetch the output signal in a period in which the first enable signal transitions from a deactivated state to an activated state.
