  "textContent": "A semiconductor device is provided for measuring a voltage of each of plural unit cells series-coupled in multi-stage and configuring an assembled battery. The semiconductor device includes two terminals coupled to two nodes which are electrodes of a unit cell and coupled with other unit cells, and a voltage measurement circuit which measures the inter-terminal voltage between the two terminals. The device also includes a down-convert level shifter circuit which converts the inter-terminal voltage into a low-potential-side inter-terminal voltage based on a ground potential, and a comparator circuit which compares the converted low-potential-side inter-terminal voltage with a predetermined reference voltage. The semiconductor device further includes an up-convert level shifter circuit which converts a low-potential-side shunt control signal based on the ground potential into a high-potential-side shunt control signal, and a switch which short-circuits the two terminals via a resistor based on the converted high-potential-side shunt control signal.",
