Automotive system design—never a task for the faint of heart—got a lot tougher last year with the release of new safety standards for electrical systems (ISO 26262). Today, analog integration is helping engineers stay ahead of these requirements and quickly changing market needs.

Electrical Vehicles

Battery-pack design is notoriously difficult. The system must continuously measure small changes in cell capacity in the face of extreme magnetic fields and voltage transients. And it needs to do this quickly to achieve the highest Automotive Safety Integrity Level (ASIL).
At Maxim Integrated, we've been working on these types of problems for two full decades. In 2010, we introduced a battery sensor that integrated all measurement, diagnostic, and communications functions in a single chip. This cut battery-management system (BMS) cost by 80%. In the next generation, we're adding a host of ASIL-enabling features to speed safety certification.

Safety Systems

Today, cameras and sensors throughout the vehicle are generating more data than ever. In-vehicle networks must be faster to get this information where it's needed, when it's needed.
Our gigabit-multimedia serial link (GMSL) gives customers a high-bandwidth pipeline for megapixel cameras and multimedia content. Several proprietary technologies are integrated to enable the use of inexpensive coaxial cable.
We're also working on sensor integration, bringing the gyroscope, magnetometer, and accelerometer together for improved data fusion. This integration is critical to efficiently process multiple sensor inputs and quickly take corrective action.

Infotainment and Access

Digital TV, analog and digital radios, and telenav—with the numerous transceivers and tuners in today's automobiles, system designers are looking for integrated solutions to reduce space and cost.
We offer complete RF-to-bits tuners that simplify the implementation of software-defined radios. This architecture enables designers to eliminate the many specialty processors in infotainment systems in favor of a multicore multimedia processor.
Other products like our keyless-go SoCs combine industry-leading integration with exceptional operating characteristics. Offering twice the range of competitors, they enable automotive designers to use fewer transceivers while improving overall system performance.
