Fully certified FlexRay transceiver enables ESD robust in-vehicle communication
It enables very high data rates of up to 10Mbit/s for in-vehicle communication and features best-in-class ESD rating of +/-10kV. As an interface between the communication controller unit and bus wires, the TLE9221SX transceiver was developed for use in suspension and chassis control applications as well as for power steering, engine and transmission control units.
As data exchange between Electronic Control Units (ECUs) steadily increases in modern cars, in-vehicle network architecture grows more complex. Multiple network interfaces that support different operating requirements are now common, with LIN bus networks handling low speed data exchange up to 20kbit/s and CAN bus networks handling medium speed up to 1Mbit/s. The FlexRay bus is now being adopted by car manufacturers for in-vehicle network architecture applications requiring very fast data rates and even real-time or failsafe data transmission.
The TLE9221SX has very low electromagnetic emissions and therefore supports large networks and complex bus topologies. It is also optimized for high immunity against electromagnetic interferences (EMI) and as a result the device passed the electromagnetic compliance (EMC) tests at the Germany-based Ingenieurbüro für industrielle Elektrotechnik/Elektronik (IBEE). The 16-pin chip is pin-compatible and footprint-compatible to other FlexRay transceivers available on the market, it can also be placed on a 20-pin FlexRay transceiver footprint. Its bus pins are protected against short circuits to positive as well as negative battery voltage levels. The device offers over-temperature protection including an integrated thermal shutdown. The transceivers are shipped in an RoHS compliant PG-SSOP-16 package
