Tool/software:
Hi TI Team
As described in DS,The input voltage of TPS3870-Q1 VDD is up to 5.5V.We use this device to detect overvoltage in a ASIL B system,and we need to know what will reset pin happen if the VDD is exceed 5.5V,for examlpe up to 12V(If LDO was break and the high volate supply to device directly). The reset pin can be actived in that situation?
Is any functional mannual about this device?
Looking forward to your reply.
Hi Devin,
Exceeding the absolute maximum rating of 6V can cause irreversible device damage and is not recommended by TI. I would recommend swapping to a 65V capable device (able to handle both the 12V battery rail and and voltage transience).
We have our TPS3762-Q1 (ASIL-D functional safety compliant wide Vin supervisor) that has all of the functional safety calculations provided (FMEDA, functional safety analysis report, safety manual, and safety report). This information can be requested on the product folder:
We also have a functional safety capable device the TPS3760-Q1, more specifically the overvoltage OPN is TPS3760E012DYYRQ1. This device provides functional safety FIT rate, FMD, and FMA functional safety documentation. This information is available in the product folder under technical documentation:
Thanks,
Joshua
