  • Patent number: 10777947
    Abstract: A universal serial bus (USB) cable including a power conductor configured to transmit power between a first device and a second device, a configuration channel (CC) conductor configured to allow the first device and the second device to determine whether a connection has been established via the USB cable, and a first positive temperature coefficient (PTC) element coupled to the CC conductor and configured to mitigate current flowing through the CC conductor if a temperature of the first PTC element rises above a predefined trip temperature.
    Type: Grant
    Filed: February 26, 2019
    Date of Patent: September 15, 2020
    Assignee: Littelfuse, Inc.

  • Patent number: 10424915
    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.

  • Patent number: 10389106
    Abstract: A cable including a power conductor configured to transmit electrical power between a first device and a second device, a first data conductor configured to transmit data between the first device and the second device, and a first protection circuit coupled to the first data conductor and associated with a first temperature sensing element, the first protection circuit configured to mitigate current flowing through the first data conductor if a temperature detected by the first temperature sensing element rises above a predefined first trip temperature, wherein the opening of the first data line indicates a fault condition to a device to which the cable is connected, whereby electrical power flowing through the power conductor is resultantly mitigated.
