Abstract
In one embodiment, a circuit includes a measuring circuit coupled to an accumulator cell. A first output of the measuring circuit outputs a current signal based on a cell voltage of the accumulator cell. The circuit includes an interface circuit coupled to the first output of the measuring circuit and a second output of a level-shifter circuit configured to change a voltage level on the first output at the interface circuit. The level-shifter circuit includes a first input coupled to the first output and one or more transistors coupled in series with one or more gate terminals that are each coupled to each of one or more terminals of the accumulator cell.
