Zusammenfassung:	A battery management system, BMS, integrated circuit, IC, (102) for a battery pack. The battery pack (101) comprises a sequence of battery cells connected in series; and a sequence of battery-cell-connection-nodes between adjacent battery cells. The BMS IC (102) comprises: a sequence of cell-measuring-pins (104) for connecting to corresponding battery-cell-connection-nodes; a plurality of bi-directional ESD protection elements (105), each one connected between a pair of adjacent cell-measuring-pins (104) in the sequence; a sequence of cell-balancing-pins (106) for connecting to corresponding battery-cell-connection-nodes; and a plurality of dual polarity switches (107), each one connected between a pair of adjacent cell-balancing-pins in the sequence.
