Abstract
The invention relates to circuits for managing differential voltages in series. To individually control the differential voltages of voltage sources in series, there is provided an integrated control circuit for a set of N sources in series. This circuit comprises N discharge control and measurement cells which are each produced in a separate well, insulated from the substrate and from the other wells. The cells are linked to the circuits formed in the substrate by level translation circuits having a part inside the well and a part outside the well. These circuits use transistors withstanding voltages of several tens of volts. The integrated circuits may be cascaded on an SPI bus if one wishes to control a group of k.N sources with k>1.
