Single-pole double-throw switch circuit with type-c interface, analog switch chip, and electronic device

A single-pole double-throw switch circuit with a Type-C interface, comprising a digital path and an analog audio path that are configured to be turned on in a time-multiplexed manner and are connected to the same COM port, wherein:

• two pins of the COM port are connected to a D+ pin and a D− pin of the Type-C interface respectively;
• the analog audio path is provided with a first field effect transistor, the analog audio path being through a source of the first field effect transistor and a drain of the first field effect transistor;
• a PN junction between a substrate of the first field effect transistor and the source of the first field effect transistor forms a first diode;
• the substrate of the first field effect transistor is a first terminal of the first diode, and the source of the first field effect transistor is a second terminal of the first diode;
• the single-pole double-throw switch circuit with a Type-C interface further comprises a reverse bias voltage module;
• and
• the reverse bias voltage module is connected between the first terminal and the second terminal of the first diode for generating a reverse bias voltage across the first diode.
