Abstract
A device suitable for charging a battery includes at least a first and a second transistor. The transistors are connected to an input voltage and have output terminals; the output terminal of the first transistor is connected to the battery. The device comprises a circuit for driving the transistors and the drive circuit comprises a regulator suitable for regulating the current in the battery during the charging phase of the battery. The regulator is suitable for keeping the voltage on the output terminals of the transistors the same during the charging phase of the battery.
