ACTIVE CELL BALANCING

An integrated circuit includes first, second, third, and fourth transistors, and a control circuit. The first transistor is coupled between a first battery terminal and a first inductor terminal. The first transistor has a first transistor control terminal. The second transistor is coupled between the first inductor terminal and a second battery terminal. The second transistor has a second transistor control terminal. The third transistor is coupled between a third battery terminal and a second inductor terminal. The third transistor has a third transistor control terminal. The third battery terminal is coupled to the second battery terminal. The fourth transistor is coupled between the second inductor terminal and a fourth battery terminal. The fourth transistor has a fourth transistor control terminal. The control circuit has a control input and first, second, third, and fourth control outputs that are respectively coupled to the first, second, third, and fourth transistor control terminals.
