Abstract: In one embodiment, a (pre)driver circuit includes first and a second output terminal for driving an electronic switch that includes a control terminal and a current path through the switch. The arrangement can operate in one or more first driving configurations (e.g., for PMOS), with the first and second output terminals are coupled to the current path and the control electrode of the electronic switch, respectively, and one or more second driving configurations (e.g., for NMOS, both HS and LS), wherein the first and second output terminals of the driver circuit are coupled to the control electrode and the current path of the electronic switch, respectively.

Abstract: A method of operating a battery management system is disclosed. A first voltage drop is sensed between a first terminal of a first battery cell and a second terminal of the first battery cell and a second voltage drop is sensed between a charge distribution pin and the second terminal of the first battery cell. The charge distribution pin is coupled to the first terminal of the first battery cell through a resistor. A difference is calculated between the first voltage drop and the second voltage drop and a faulty condition is detected when Rn absolute value of the difference between the first voltage drop and the second voltage drop exceeds a threshold.
