onsemi Solutions for Automotive IVN & Lighting
onsemi Solutions for Automotive IVN & Lighting provides energy-efficient solutions for automotive In-Vehicle Networking (IVN) and lighting to reduce emissions, improve fuel economy, and enhance lighting, safety, connectivity, and infotainment power delivery systems. These cost-effective in-vehicle networking (IVN) and lighting solutions offer low power consumption and high reliability.
In-Vehicle Networking
A luxury car or SUV can have more than 70 pounds of copper wire in it, not including the relays or fuses. By using onsemi IVN products, automotive engineers can eliminate this wire, reducing automotive costs and waste, by using components that reduce the number of wires needed to connect systems throughout the vehicle.
onsemi supplies products and solutions that support a broad base of network options, from simple messaging to fail-safe messaging. onsemi offers extensive products for local interconnect networks (LIN) and controller area networks (CAN). The ability to create systems-basis chips (SBCs) from analog IP allows for a wide variety of connectivity applications in the vehicle. Beyond LIN and CAN, onsemi supports FlexRay for control of powertrain safety-critical activities, as well as Ethernet for active safety requirements.
FlexRay In-Vehicle Networking
onsemi FlexRay transceivers are fully compliant with the FlexRay Physical Layer Specification V3.0.1. The transceiver is a bus driver (BD), and it creates the physical interface between the communication controller and the bus medium. Designed for critical powertrain and safety information, these FlexRay transceivers realize bus communication without data collision.
LIN and CAN In-Vehicle Networking
onsemi LIN and CAN transceivers offer a cost-effective means for basic and efficient communications within light vehicles. onsemi offers a wide portfolio of LIN devices, all compliant with LIN V2.X, J2602, and ISO17987-7:2016. CAN devices from onsemi meet all ISO11898-2:2016 requirements, and are designed for superior ESD and EMC performance. The portfolio supports both body and powertrain-focused applications, and includes low-speed, high-speed, and CAN-FD transceivers in a variety of advanced packages.
System Basis Chips
onsemi SBCs provide a cost-effective, high-performance, reliable approach to multiple LIN and CAN configurations. These devices support linear voltage regulation, controlled through an SPI interface. onsemi SBCs offer various power-saving modes, including standby, sleep, stop, and other power features such as wakeup and watchdog timer.
Lighting
Advanced LED lighting systems in vehicles are helping to reduce nighttime accidents. onsemi supplies products and solutions that control individual LEDs to complex LED lighting strings. The company designs LED drivers and power supplies for all forms of automotive lighting, including interior, RGB, accent, and complex rear tail lights, as well as scalable systems for advanced LED mechatronic and pixel front-lighting systems (PFLS). In addition to lighting solutions, onsemi offers SPI and LIN motor control options for tilt and swivel control within the front lamp assembly.
Advanced Front Lighting Systems
onsemi advanced front-lighting systems (AFLS) utilize a combination of sensors, motors, and an LED matrix to adjust the direction and intensity of the light beam. As a leader in automotive LED lighting solutions, onsemi offers a wide portfolio of products and solutions that enable the growing automotive advanced front lighting market. These solutions include power management ICs (DC-DC current source), pixel controllers, and stepper motor drivers for tilt and swivel. onsemi products support modular designs, allowing for a different number of LED strings, as well as flexible design options, supporting multiple car platforms with the same electronics.
Exterior Lighting
onsemi provides a variety of discrete, linear programmable constant current devices designed for the regulation and control of LED-based lighting systems. These linear current regulators and controllers are able to drive rear combination lamps, daytime running lights, and turn signals. They allow for two programmed levels for stop and tail illumination, and also slew rate control to eliminate EMI concerns.
Interior Lighting
onsemi features a variety of discrete and monolithic solutions for a full range of applications. These include simple solutions such as two-terminal constant current regulators (CCRs), which are economical, robust devices that provide an effective solution for regulating current in cost-sensitive automotive LED applications. More complex solutions include LIN RGB LED drivers that combine a LIN transceiver with an RGB LED driver and memory, providing a single-chip RGB driver intended to monitor dedicated multicolor LED applications.
