The Bus Driver (BD) realizes the physical interface between a FlexRay node and the communication channel. It provides differential transmit and receive capability to the bus, allowing the node bidirectional time-multiplexed binary data stream transfer. In addition to transmit and receive functions, the TLE9222 provides low power standby operation, supply voltage monitoring (undervoltage detection) as well as bus failure detection and represents an ESD- protection barrier between the bus and the ECU. The TLE9222 supports the following FlexRay functional classes: Functional class Bus driver - bus guardian interface Functional class Bus driver logic level adaptation Functional class Bus driver remote wakeup Functional class Bus driver increased voltage amplitude transmitter In BD Standby mode the quiescent current is decreased to a minimal level while still being able to detect wake-up requests on the bus. Fail Safe features, like failure detection and the power supply monitoring, combined with an easy accessible status register support requirements for safety related applications with extended diagnostic features. The TLE9222 is internally protected against transients on the bus pins, BP and BM. This makes it possible to use the TLE9222 for implementing ECUs without additional external bus protection circuitry while fulfilling ESD and ISO pulse requirements of car manufacturers. With its excellent EMC performance the TLE9222 provides a very high immunity against RF disturbances over a broad frequency range and transmits only a minimal level of electromagnetic emission onto the bus. The TLE9222 is integrated in a RoHS compliant PG-TSSOP-14 and PG-TSON-14 package. Using the latest Infineon Smart Power Technology it is especially tailored to withstand the harsh conditions of the automotive environment and qualification according to the AEC-Q100 standard.
