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 predefine trip temperature.
Claims9
A system for providing over-temperature protection comprising:
- a first device having a first data conductor,
- a second device having a second data conductor,
- a cable comprising:
- a power conductor connecting the first device to the second device and configured to transmit electrical power between the first device and the second device;
- and
- a third data conductor connecting the first data conductor to the second data conductor and configured to transmit data between the first device and the second device;
- and
- a first positive temperature coefficient (PTC) element coupled to the first data conductor and configured to mitigate current flowing through the first data conductor if a temperature of the PTC element rises above a predefined first trip temperature, wherein at least one of the first device and the second device is configured to reduce an amount of electrical power transmitted via the power conductor upon mitigation of the current flowing through the third data conductor.
