Abstract
An overcharge protection circuit comprises a first series of first terminals a second series of second terminals, a first overvoltage protection device connected between each consecutive pair of first terminals, a current balancing device connected between each consecutive pair of second terminals, and a second overvoltage protection device connected between a first terminal and a second terminal. The second overvoltage protection device is configured to pass a current if a voltage over the second overvoltage protection device exceeds a threshold. The second overvoltage protection device may comprise a bidirectional ESD diode, while both the first overvoltage protection device and the second overvoltage protection device may comprise a unidirectional ESD diode.
