Faster?functional safety?system certification

bitfinex www.xingyunzhuwang.com Efficiently achieve ISO 26262 and IEC 61508 certification and more, using our products, available documentation and knowledgeable safety experts.

Meet the rigorous requirements of functional safety standards, such as ISO 26262 and IEC 61508 with our analog and embedded processing products. While all of our products follow our certified quality-managed processes, we understand that safety critical functions require more rigor. This is why our functional safety-compliant products leverage our TüV SüD-certified functional?safety?hardware?and?software?development processes.

Let us help you achieve the highest ASIL and SIL levels your design requires. In addition to our functional safety-certified engineers, available documentation and resources such as functional safety FIT rate, FMEDA, safety certificates and software diagnostics libraries help you streamline the certification process.

The chart below lists the development process and documentation you will find in each of our functional safety product’s technical documentation section.

Products for functional safety

Your design starts with finding the right parts.?Start exploring our most robust, functional safety-compliant and functional safety quality-managed products, many designed with integrated safety mechanisms to help detect and prevent dangerous failures resulting from systematic or random hardware faults, ultimately helping you achieve up to ASIL-D or SIL-3 functional safety system certification.

Explore featured applications

Leverage our interactive system block diagrams to find the product, reference design or design resource for your automotive or industrial functional safety application.

Automotive

Advanced electronic components are reducing vehicle emissions, improving connectivity and enabling levels of autonomous driving. With so much at stake behind the wheel, functional safety provides the necessary risk management framework. Your designs can meet ISO 26262 requirements and automotive safety integrity levels (ASILs) up to ASIL D with our devices, tools and design resources.

Industrial

Industrial systems from Industry 4.0 to robotics and motor drives are getting smarter, safer and more efficient. The demand to design safer industrial systems, reduce manufacturing downtime and maximize the lifespan of equipment increases functional safety design requirements to meet standards such as IEC 61508, ISO 13849, IEC 61800 and IEC 60730. Find the products and resources you need to meet your toughest industrial system-level design challenges.?

Frequently asked questions

Still have questions? Find your answer here or search the?bitfinexTI E2E? technical support forums?where our engineers answer your questions and share their knowledge.

Which standards do our parts comply with?

IEC 60730 –?Applies to automatic electrical controls for use in, on, or in association with equipment for household and similar use. This standard also applies to automatic electrical controls for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications.

IEC 61508 – Covers functional safety aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions.? This standard can be applied to a large range of industrial applications and also provides a basis for many other standards.

ISO 26262 – Applies to functional safety-related systems that includes electrical and/or electronic (E/E) systems and that are installed in series production automotive vehicles.

?

Is the functional safety FIT rate different than the technology FIT rate? How is functional safety FIT-rate calculated?

Yes, the functional safety FIT rate is different than the technology FIT rate. Our functional safety FIT follows IEC TR 62380 and, by request, SN 29500. Because of the differences in how the functional safety FIT rate is measured, the results using our technology FIT rate calculator will not be what you need for your functional safety system.

?

What’s the difference between FMEA and pin FMA?

Both reports are the results of failure mode analysis. The report content and format are different.

An FMEA report follows a process and format that is required by the IATF 16949 standard for automotive product development using the AIAG FMEA requirements standard.? When a failure mode analysis report does not follow the AIAG FMEA process and format it is called a pin FMA.?

?

Why do some of your products offer the FMD and pin FMA, but some only have one or the other?

Providing a pin FMA is required when you have dedicated single function pins that can be easily mapped to a specific failure mode. In contrast, for a microcontroller or processor device the IO’s are typically multi-function and have several layers of in-built pin muxing, meaning that there is no single function and no practical means of mapping a single IO to a single specific failure mode.

In this scenario each pin is assumed to have the same potential for failure and therefore an equal failure rate. Within our FMEDA the package failure rate is calculated as per the IEC 62380 model and then equally divided by the number of pins to provide a FIT per pin failure rate. The FMEDA allows the customer full control over the package failure rate through the applied diagnostic measures down to the individual pin level. Finally, failure modes of IP that include failures of the pins are covered in the analysis of individual IP and a further pin FMA would be redundant.

?

What should I do if a product I’ve selected does not have an analysis report available?

Please contact your local sales representative.

Where can I find SafeTI products?

While we are no longer using the brand SafeTI, these products are still supported and available! If you were using or considering a SafeTI-26262 or SafeTI-61508 product, you will find them under the functional safety-compliant category. If you were using or considering a SafeTI-60730 or SafeTI-QM product, you will now find them listed as functional safety quality-managed products.?
