Digital temperature indicators protect USB power delivery systems from overheating. The devices do this by exponentially increasing their resistance and reducing the flow of current when the temperature of a USB charging circuit rises above a set point. The setPTM digital temperature indicators made by Littelfuse are optimized to protect USB Type-C plugs with captive cables while handling the heaviest USB-PD loads.
