NXP supports automotive industry move to 48V on-board supply with industry-first 60V FlexRay transceivers

EINDHOVEN, THE NETHERLANDS: NXP Semiconductors announced the availability of a new family of FlexRay transceivers that supports the automotive industry move towards a 48V board net in future vehicles. The new 48V FlexRay products complement NXP's existing portfolio of 48V CAN transceivers.

Last year, at an international automotive electronics congress in Ludwigsburg, Germany, the top five German carmakers BMW, Audi, Daimler, Porsche, and Volkswagen had jointly announced their agreement to take this step. NXP's transceivers are the industry's first that are capable of supporting the new board net by offering up to +/-60V robustness.

As the electrification of previously mechanical functions within vehicles continues, from power steering to the power train and vehicle dynamic systems, the standard 12V board net has reached its limit. Rather than increasing the cable diameters in 12V systems, automotive manufacturers are now determined to standardize on 48V instead. This step will ensure efficient power supply to all high-current devices. OEMs also expect that 48V systems would reduce CO2 emissions based on optimized recuperation, replacement of hydraulics in power steering, and improved air conditioning. At the same time the 48V board net would reduce the weight and footprint of high-power actuators.

NXP is once again demonstrating leadership in in-vehicle networking by being the first company to deliver robust FlexRay transceivers capable of supporting the upcoming 48V standard without the need for expensive external decoupling devices. Offering reduced CO2 emissions due to very low current consumption in standby and sleep mode plus high immunity to ESD, the new transceivers highlight NXP's high performance mixed signal strategy. While other companies continue to design using lower voltage CMOS processes, NXP's ABCD3/9 technology offers high voltage features far beyond 60V at a high density of digital logic.
