Hello,

can you please help me to classify the TLVH431 device according the SN 29500 standard? I have to perform an FMEDA analysis with the tool Silcal and the classification for each component is required.

Hi Fulvio,

Thanks for your question!

Unfortunately, this device is not intended for functional safety.

What is the application for the TLVH431 in the system? If it is utilized for voltage supervision, we have a number of devices that are functional safety compliant that can help.

One example is the TPS3762 as shown below:

I hope this helps!

Hi Andrew, thank you for your reply.

The device is used as voltage reference, not as voltage monitoring, and it is part of a more complex circuit.

Can you please give me its classification according to the Siemens SN29500 standard?

Thanks and regards,

Hi Fulvio,

Thanks for your patience.

I just checked with the team, and this device should be classified as a linear IC. You can find the FIT rate at the link below. I do not have any additional information to share.
