摘要： Electrical apparatuses with connector overheating protection and methods for protecting electrical apparatuses from connector overheating during current sinking and current sourcing operations are presented. The electrical apparatus includes an electrical connector and a temperature sensor, which is in direct contact with a physical part of the electrical connector. The temperature sensor monitors a temperature of the electrical connector during current sinking and current sourcing operations. During current sinking, if the temperature sensor senses a predetermined level of overheating of the electrical connector, then the sourcing of current to the electrical apparatus is switched off. During current sourcing, if the temperature sensor senses a predetermined level of overheating of the electrical connector, then the sourcing of current to the sinking device is switched off. Switching off the source of current prevents overheating of the electrical connector and protects the electrical apparatus during current sinking and current sourcing operations.
