Abstract
A control circuit for controlling current of batteries at the end of the charging phase, especially for lithium batteries, including an input/output circuit, placed between a battery charger and a battery, and an output stage, including two transistors, wherein the resistance of one of the two transistors is modulated to increase the value of the total resistance and to cause a lower turning off current of said output stage.
