Automated Driving & the need for safe electronic systems
The future of mobility is driven by megatrends such as automated driving and connectivity, which will further increase the demand for secure electronic systems in the upcoming years. These systems require highly integrated and safe electronic semiconductors.
The ISO 26262 standard is an automotive specific adaption of the IEC 61508 and was introduced to reduce risks of failure by defining objectives for systems and components. At Infineon, we believe in a holistic approach towards Functional Safety as the basis for dependable electronics. Today, we provide ISO 26262 ready and compliant products for the automotive market for all safety-relevant applications.
Automotive Functional Safety and ISO 26262 regulations
Today’s standard for automotive safety supporting automated and autonomous driving systems is the ISO 26262:2018 which is already deeply embedded in Infineon’s automotive development processes and related support activities to achieve product compliance.
Our customers benefit from:
- Innovative solutions for safety critical applications
- Reduced time-to-market through safety documentation with ISO 26262 compliant products
- Low effort on integrator level with ISO 26262 ready & compliant products
- Broad portfolio of ISO 26262 compliant products already available
- Newly developed parts will primarily be part of an ISO 26262-compliant development flow without additional charge
Design your safety-critical system with Infineon today
Our mission is to facilitate the path towards the safety compliance of a system in conformance to the functional safety standard.
The increasing complexity of safety standards/applications and more stringent requirements make functional safety integration costly and time-consuming. For an easy integration and a minimum effort at system integrator level, Infineon provides the necessary supporting information and documentation.
With the different PRO-SIL™ levels, we help to find the right level of support and documentation reducing your efforts to a minimum and lowering implementation cost.
A clear guidance regarding ISO 26262 compliant products
* Safety Application Note: Safety Analysis is conducted by Infineon – Evaluation of components is part of the integrator’s responsibility
** Safety Manual contains all necessary data for your safety integration & safety analysis
Both, ISO 26262-compliant and ISO 26262-ready classifications are recognizable by the PRO-SIL™ trademark.

Smart window lift module
Another prominent example is the anti-pinch protection for power windows, which brings safety aspects into play to protect passengers from harm. Integrated diagnosis capabilities e.g. current sensing, over and under voltage, over temperature protection and a device watchdog help to protect the system from unintended behavior.
In addition to the functional safety aspect, space is always a critical factor in intelligent window regulator applications. The ideal result: a system-on-chip solution at a low price - with a small form factor to save valuable PCB board space. A single- chip solution for improved module reliability is in high demand. To meet your smart window lift requirements, Infineon offers high-quality semiconductors and a chip with a small form factor and a small package.
System benefits
- System-on-chip solution with integrated ARM® Cortex®-M0industry-standard microcontoller core
- Platform solution for a size- and weight-optimized relay-based motor control
- Integrated voltage regulator, LIN transceiver, switch inputs and relay driver
- Integrated current sense and clock independent watchdog functionality
- Cyclic sense and cyclic wake-up capability saves average current consumption
- Single-chip solution improves module reliability

Seat control module
High-end seats combine applications for: Seat adjustment or seat movement and Seat comfort. Seat safety functions must be implemented e.g. to prevent unintended movement of the seat.
As modern seat modules take on additional functions, they have a comparable complexity to body control modules with similar challenges in meeting requirements for supply, communication, sense, actuation and control, and quiescent current targets.
With Infineon’s products, seat control modules can be implemented in the smallest space and with the lowest power dissipation and low quiescent current.
System benefits:
- Highly integrated systems enable multiple level of seat comfort and safety
- Creates more cabin space, as smaller footprints and lower profiles of semiconductors allow thinner ECUs and therefore thinner seats
- Avoids irritation of the driver by relay clicking, which is necessary when the vehicle become quieter (e.g., hybrids, EVs and cars with start/stop function)

Fail-operational electric power steering (EPS)
Fail-operational electric power steering (EPS) is a safety critical application, particularly in cars that are becoming more and more autonomous. In the highly unlikely event of a system failure, the redundant system ensures that EPS will continue to function. Besides fulfilling safety requirements, a fail-operational design also provides all the advantages of a standard EPS system.
System benefits
- Powerful & scalable system & proven interoperability
- Support of nx3 phase based fail- safe and fail-operational EPS systems
- Aligned safety concept of power supply and microcontroller
- Adaptable via software to suit a range of car models and driving modes
- Upgradable to meet future requirements, such as steer by wire for automated driving
As the ideal chipset for fail-operational EPS systems, Infineon manufacturers the full range of ICs, including safety microcontrollers, power supplies, bridge drivers, world-class MOSFETs and sensors.
