Original question:

Short to VBUS protection for USB Type C TX/RX pins

TPD6S300A: Steady State Short to Vbus on D+ & D- Pins in USB-C

Part Number: TPD6S300A

Most USB Type C Port Protector provides ESD protection on D+/D- USB lines which will protect against transient over voltage but not steady state short to Vbus.

TPD6S300A USB Type C Port Protector addresses steady state short to Vbus for  CC pins but not for D+/D- pins. I believe that short to Vbus is likely on D+/D- USB lines as well due to fault cable, cable puncture or water ingress.

Is there a USB Type C Port Protector that address steady state short to Vbus for both D+/D- & CC pins ?

    Hi,

    The reason we advertise CC and SBU protection is because those pins are the closest in proximity to the VBUS pins, and are the most likely to be damaged in a faulty cable scenario.

    Regardless, the TPD6S300A can actually support short to vbus on the D+/D- by connecting those pins in replacement of the SBU pins.

    Let me know if any further questions.

    Thanks,

    Matt
