The electronics industry has historically been driven by the need for cheaper, smaller, lighter, and higher-performing technology. Continuously improving these metrics while ensuring that the technology will have relevancy, flexibility, and prominence in the future has been, and continues to be a significant challenge for design engineers. The automotive sector is an ideal industry to observe how changes in technology can drastically alter the user and manufacturing experience.

Since the start of the 1900’s practical advancements such as air conditioning, ABS systems, and power steering have made the driving experience safer and more economic. With a rapidly growing number of electronically controlled systems implemented in the automobile, there came an obvious need to reduce the amount of direct wiring that existed between these systems to reduce the time and money spent during the manufacturing process and simplify the system failure debug process.

In 1986 BOSCH released the Control Area Network (CAN) bus. This protocol defined how Electronic Control Units (ECU) could communicate without the need for a host computer. This allowed devices, sensors, and microcontrollers to talk over a communication bus, diminishing the need for direct connections across the automobile and aiding in the reduction of vehicle cost, weight, and complexity.

In the past two decades, the CAN bus has been a part of mandatory standards inside the United States. The last two decades have also given rise to a complementary serial network protocol Local Interconnect Network (LIN). The LIN bus offers an even cheaper and simpler network designed to complement existing CAN systems, often used for controllers that are do not require high reliability and data rate.

ON Semiconductor offers an innovative in-vehicle portfolio, including LIN, CAN, and FlexRay™ transceivers. ON Semiconductor also offers System Basis Chips that integrate transceivers with other circuits, including voltage regulators, drivers, and supervisory functions.  Please see the Automotive Products Selector Guide to help find the ideal device for your design.
