Hi
We would like to implement automotive type-c solution with TPS2580-Q1 how we add external protection IC or discrete parts for ISO 16750-2 "36V short to VBATT protection/isolation"?

Vincent
Hi Vincent,
We seems to not have such high protection device, let me double confirm with Leanne, and give some feedback to you today, thank you.

Hi Vincent,
What voltage is primary power source? In Automotive applications this is typically 12V -16V. In this case, Short to VBATT protection requires up to 18V OVP. You can consider TPS25830A-Q1 to implement Automotive Type C solution with Short-to-VBATT and IEC 61000-4-2 ESD protection. TPS25830A-Q1 is next gen of TPS25810-Q1, integrating with robust protection and Buck converter in one-chip.
What's your application and which pins of Type C connector you want to have protection on?
If including CC1,CC2 pins, we have discrete protection part, like TPD6S300A AND TPD4S311A. They support CC1,CC2,SBU1,SBU2 or CC1,CC2,DP,DM Short-to-VBUS 24V tolerant OVP and IEC ESD protection. These two parts are not Automotive grade.
If not including CC1,CC2, TPD2S703-Q1 is protector for Short-to-VBAT and IEC ESD protection on DP,DM.

Hi Leanne
Our target is USB 3.0 type-C (without PD) implement with 24V automotive battery. Follow the ISO 16750-2 requirement, the shot to battery test will be performed up to 36V.
The TPS25830A-Q1 support short-to-battery protection on VBUS, CC1, CC2, DM_IN and DP_IN pins but only up to 18-V tolerance not meet our requirement. Therefore, we need to consult with TI's expert if any feasible discrete parts could meet our requirement?

Hi Vincent,
Thanks for the info about your application. Understand this is a 24V automotive battery.
I have a roadmap device to support this application on 24V battery. Could you please provide me the email address or your company? TI Field resource will contact you with introduction to pre-production part.

Hi Leanne
My TI FAE contact window is Eddie Chou. I also consult with him (off-line) for the new part released on coming Q3,
However, we want to check if any possibility to design with discrete (protection) parts?

Vincent
Hi Vincent,
Our new device will be sampling in 1Q24.I sent out introduction of the new device to Eddie Chou. He might share with you later.
