Abstract
This invention discloses an electronic device, a signal switching method, and a power supply method. The electronic device, featuring a connector supporting multiple connection standards, includes a connector, a first multitasking circuit, a processor, and a controller. The connector includes a detection pin and at least one signal pin. The first multitasking circuit is coupled to the at least one signal pin. The processor is coupled to the first multitasking circuit. The controller monitors the detection pin. The first multitasking circuit electrically connects the at least one signal pin to the controller. When the detection pin detects a hot-plug signal, the controller sends an acknowledgment command via the first multitasking circuit and the at least one signal pin to request a device signal response. Upon receiving the device signal, the controller controls the first multitasking circuit to electrically connect the at least one signal pin to the processor or controller based on the device signal. This device enables a single connector to support multiple connection standards and reduces costs.
