Abstract
An electronic device and a method of a power supply protection for a connection port are provided. The electronic device includes a first connection port with a first switch and a first controller and a first control circuit. The first controller determines a first preset value according to a state of the first switch activation signal correspondingly, and detects whether the first input voltage of the first connection port is greater than the first preset value. When the first input voltage is greater than the first preset value, the first controller enables a first abnormal signal on the first abnormal state detection pin. In response to a first forced closing signal being enabled, the first controller controls the first switch to disconnect both terminals.
