Hi Gareth,

Here are the available automotive Type-C port protection devices.

https://www.ti.com/product-category/interface/usb-ics/usb-port-protection-ics/products.html#1498=Automotive&1918=USB%202.0%3BUSB%203.0%3BUSB%20Type-C&2192=Current%20limit%3BOvervoltage%20protection%3BShort-to-VBUS%3BShort-to-battery%20protection&

TPD4S201-Q1, TPD4S480-Q1, and TPD4S481-Q1 are the latest devices. My product line doesn't cover the USB3.0 data lines (SSTX/SSRX). These are AC coupled and DC short to VBAT will be blocked by the series capacitor. It may be worth considering a low capacitance diode on the protected side of the capacitor.

I don't have anything to offer in terms of automotive HDMI short to VBAT protection.

Low capacitance USB3 diodes and Ethernet ICs are handled by different product lines. I suggest finding a device through ti.com and submitting a new ticket in that product category if more assistance is required. I am not knowledgeable in these devices myself.

Regards,
Eric
