Functional safety technologies

Industrial and automotive functional safety motor-control resources

If you are designing industrial and automotive motor control applications that include variable speed drives and automotive traction inverters, you need to comply with functional safety standards such as International Organization for Standardization (ISO) 13849, International Electrotechnical Commission (IEC) 61800-5-2 and ISO 26262 to ensure correct operating procedures and keep operators safe. Our semiconductor isolation technologies with increased lifetimes help meet your isolation requirements and enable highly reliable systems, while sensing and real-time processing for monitoring faulty scenarios and actuating to a safe state help reduce the overall risk of hazards.

Integrated processing

The integrity of the processing block is important in the signal chain – from sense to process to actuate – for compliance with functional safety requirements. Our processors have a safety architecture with built-in hardware features for executing software, and our processing units support symmetric or asymmetric redundancy to enhance system integration. In microcontrollers (MCUs) with symmetric redundancy, lockstep or dual-core mode configurations support different levels of safety integrity functions at the system level and trade off with processing power to enable the implementation of automotive (ISO 26262) and industrial or machinery (IEC 61508, ISO 13849) system architectures.

Scalable power supply

Safe power designs require uncompromised performance, along with fail-safe mechanisms to comply with functional safety standards. We have a broad portfolio of switching regulators, low-dropout regulators, supervisors and power-management integrated circuits (PMICs) enabling scalable power architectures that can meet functional safety requirements. 

High-accuracy and high-speed over- and undervoltage fault detection reduce overall system failure-in-time and fault-tolerance time intervals. Pairing discrete and integrated power solutions with scalable supervisor solutions help support power designs that conform to automotive (ISO 26262), industrial (IEC 61508) and machinery (ISO 13849) standards.

Frequently asked questions

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

Which standards do your 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 and 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 online mean time between failure (MTBF)/FIT estimator for technology FIT rate is derived using the JESD85 methodology from internal high-temperature operating life (HTOL) and early life failure rate (ELFR) reliability testing. The MTBF and FIT are estimated with a 60% confidence level for reliability.

This method provides an accurate FIT rate for the process technology but does not take into account transistor or gate count, die size or other important factors. We provide functional safety FIT rate based on one of two standards, IEC TR 62380 or SN 29500, which offer a 90% confidence level. Functional safety standards, such as IEC 61508 and ISO 26262, often suggest 90% confidence levels be used for safety-related random failure FIT rate estimation.

For more on functional safety FIT rate, read this Understanding Functional Safety FIT Base Failure Rate Estimates per IEC 62380 and SN 29500. 

What is the difference between FMEA and pin FMA?

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

A failure modes and effects analysis (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?
