Abstract
An electronic device is provided. The electronic device integrates an enable function and an over-temperature protection function (OTP) on the same line, thereby reducing the PCB layout between a microcontroller and a mainboard circuit, and further reducing the circuit complexity and cost. In addition, the negative temperature coefficient (NTC) thermistor in the electronic device is also directly coupled to a circuit pin used for the enable function of the microcontroller to serve as an over-temperature protection application. Therefore, even if the microcontroller fails, the electronic device may still use the hardware circuit structure to automatically achieve the over-temperature protection function.
