Abstract
An electronic device includes an input, an output, a metal fuse, a resistor, a heat control transistor, and a heat controller. The metal fuse is coupled between the input and the output. The resistor is coupled between the metal fuse and the heat control transistor. The heat control transistor is coupled between the resistor and a reference terminal of the electronic device, and the heat controller is configured to control a heater current of the heat control transistor.
