VOLTAGE DETECTION INTEGRATED CIRCUIT AND BATTERY MANAGEMENT SYSTEM COMPRISING SAME

A voltage detection integrated circuit may include: a voltage detection circuit electrically connected to a plurality of cells to detect a cell voltage of a corresponding one of the plurality of cells; a plurality of cell balancing switches configured to conduct or block a flow of a balancing current of a corresponding cell among the plurality of cells; a temperature sensor configured to detect an internal temperature of the voltage detection integrated circuit; and a controller configured to differently select a number of cell balancing switches that are simultaneously turned on depending on the internal temperature, and to turn on the selected switches, when the internal temperature is below a first threshold value.
