Abstract
Secondary battery protection circuits for protecting a battery from charging and/or discharging faults are provided. A secondary battery protection circuit may include a first terminal and a second terminal, a transistor electrically connected between the first terminal and the second terminal, a fuse electrically coupled to the gate of the transistor, and a fuse control circuit configured to cause current sufficient to open the fuse to pass through the fuse in the event of a fault condition.
