High Speed Bus Transceiver for Automotive Networking

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 adaption to the FlexRayT communications protocol. The NCV7381 is a highly robust, single-channel device capable of data transfer speeds up to 10 megabits per second (Mbits/s). Conforming fully with FlexRayT Electrical Physical Layer Specification Rev. 3.0.1, the new device offers a differential transmit and receive capability between the wired FlexRayT communication medium and the protocol controller/host.

The NCV7381's mode control functionality is optimized 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 volt (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. Interference with neighboring circuits is reduced due to its low electromagnetic emission on the bus lines. The device also has a high degree of electrostatic discharge protection and is able to cope with in excess of 10 kilovolt (kV) ESD pulses. The NCV7381 is AEC qualified and has an operational temperature range of -40 °C to +125 °C.

The NCV7381 is supplied in a Pb-free, RoHS-compliant SSOP-16 package and priced at $1.60 for 2000 unit quantities.
