ASM330LHB-Query

[ganand05]

Dear team,

I'm using ASM330LHB for Electronics Brake control project.Please clarify my queries to use this ASIC in our application.

How the ASIC is claimed as ASIL-B? Is there any redundancy in the ASIC itself?

How the error detection and error reaction is handled & What is the safety mechanism? What is the single point & latest point fault metric?

Please share if there is any safety analysis like FMEDA & FMEA.

It would be better if u share internal block diagram to explain this.

What is your proposed interface circuit to microcontroller to achieve ASIL-D?

Perhaps conversations best had with a local FAE and/or sales representative?

Conversation with local representative is not happened. I had checked already the AN5591. Please answer mainly below questions.
