Onsemi Ships One Billionth Inductive Sensor Interface Integrated Circuit to HELLA for Automotive X-by-Wire Systems

Category articles

Onsemi, a leader in intelligent power-and-sensing technologies (NASDAQ: ON), announced today that it had shipped its billionth Inductive Sensor Interface Integrated Circuit. HELLA Automotive uses onsemi’s Contactless inductive position sensor technology for automotive x by wire systems. Both companies have developed innovative design techniques over their 25-year partnership to reduce both module and onsemi IC sizes to better meet the demands of module form factors. This was achieved through collaboration onsemi’s 1 Billionth Shipment. Inductive sensors can detect metallic objects even without physical contact. They do this by creating an electromagnetic field which induces current flow in the object.

The Inductive Sensor Interface Integrated Circuits translate the signals from an inductive sensors into formats that can be used by other electronic systems including automotive xby-wire systems. They are an integral part of the Contactless Inductive position sensor (CIPOS(r), technology that is used in drive by wire systems. This includes accelerator pedal sensing and steering torque sensors as well as pressure boost actuators, turbo boost actuators, and turbo boost actuators.

CIPOS(r), an inductive technology, is used in both passenger and commercial vehicles to drive-bywire systems like accelerator pedal sensors, steering torque sensor and actuators for turbo and pressure boost systems. HELLA’s IC is the main component and together with coils, it forms an inductive position sensors. This solution, which is contactless and has a long lifespan, will maintain its accuracy. CIPOS(r), the technology used in CIPOS, is immune to stray electromagnetic fields – a valuable asset for an industry that is moving towards electrification. HELLA is one of the major automotive OEMs that use this leading solution. It also dominates the global market for accelerator pedal sensors.
Drive-bywire systems, also known as x by wire systems, are electronic control systems that replace mechanical systems in vehicles. Drive-by-wire uses electronic signals to communicate between the driver and vehicle instead of physical connections such as hydraulics and cables.

Drive-by wire systems rely on sensors and electronic controllers that track the driver’s input and convert it into electronic signals to be transmitted to different components of the car such as brakes, steering, engines, transmissions etc. In order to regulate the operation of their components.

Drive-bywire systems offer several advantages to mechanical systems. These include improved fuel efficiency, reduced emissions, and added safety features. They are also essential in the development of autonomous driving technology.

Marco Dobrich is the Head of Sensors Business Field for HELLA. He stated that “HELLA relies on onsemi technologies and development expertise to make CIPOS (r) a leading sensing solution on the market.” Their quality levels are outstanding, and our capacity planning ensures that we remain agile in an increasingly demanding market.

HELLA and onsemi worked together for almost two decades before releasing their first automotive inductive positioning sensor in 1999. Onsemi provided HELLA three generations of inducting position interfaces since then. Each was tailored to HELLA’s specific requirements and developed in tandem.

Onsemi’s Sudhir Gopalswamy stated that the two companies would not have been able to reach this milestone if they had not worked together at a fine-grained level. They are also working on the next generation of inductive sensor technology, which will focus on system-level improvements focused around Automotive Safety Integrity Levels.
