| description | The invention discloses a USB-C control chip, a USB-C control chip protection circuit, and a USB-C system. The USB-C control chip protection circuit is characterized in that a first NMOS transistor and a second NMOS transistor are provided; the first NMOS transistor is serially connected between the first interface of the USB-C control chip and the first external element, and when the drain voltage of the first NMOS transistor exceeds the threshold voltage, the source electrode and the drain electrode of the first NMOS transistor are disconnected; the second NMOS transistor is serially connected between the second interface of the USB-C control chip and the second external element, and when the drain voltage of the second NMOS transistor exceeds the threshold voltage, the source electrode and the drain electrode of the second NMOS transistor can be disconnected. The problem of the prior art of the easy damage of the internal circuit of the USB-C control chip caused by the input high voltage can be solved. |
