A circuit providing voltage cell balancing is provided. The circuit includes a cell balancing network comprising separate switching circuits, each being configured to balance a respective cell voltage for a respective cell of a plurality of voltage cells based on a respective switching control signal. A control circuit includes a plurality of current sources, each of the plurality of current sources selectively connected to a respective one of the separate switching circuits to independently control operation of each of the separate switching circuits of the cell balancing network to balance the voltage across the plurality of voltage cells.

System and method for balancing voltages

A voltage regulator, according to the present invention, can operate with or without an external power transistor to generate a regulated output voltage. The voltage regulator determines whether an external power transistor is connected thereto. The voltage regulator then automatically sets a frequency compensation scheme that depends on whether an external power transistor has been detected.
