FlexRay transceiver

17 October 2012 Telecoms, Datacoms, Wireless, IoT

ON Semiconductor has expanded its portfolio of automotive networking products with the introduction of a bus transceiver IC that is compliant with the most recent adaptation to the FlexRay communications protocol.

The NCV7381 is a highly robust, single-channel device capable of data transfer speeds up to 10 Mbps. Conforming fully with FlexRay Electrical Physical Layer Specification Rev. 3.0.1, the new device offers a differential transmit and receive capability between the wired FlexRay communication medium and the protocol controller/host.

The IC’s mode control functionality is optimised for nodes permanently connected to car batteries. The device offers low-power operation and a low power mode receiver that allows remote wake-up detection.

Capable of running from a 5,5 V to 50 V battery supply, the NCV7381 can be integrated into both 12 V and 24 V automotive power systems. It has strong electromagnetic susceptibility (EMS) performance across its full frequency range.

The device has a high degree of electrostatic discharge protection and is able to cope with in excess of 10 kV ESD pulses. It is AEC qualified and has an operational temperature range of -40°C to +125°C.
