Patent number: 10424915Abstract: 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.Type: GrantFiled: January 9, 2015Date of Patent: September 24, 2019Assignee: Littelfuse, Inc.Inventors: Sam S. Kang, John M. Jorgensen, Bharat Shenoy, Kunghao Yu
