Brief Functional Description
The low cost bus driver is a part of the electrical, physical layer in a FlexRay™ communication network. The E910.55 provides an interface between the twisted pair physical bus medium and a communication controller (CC). An SPI interface connects the bus driver (BD) to a host controller (HOST) to provide status information concerning failure detection on the bus lines (e.g. short-circuits, ground loss) and overtemperature condition. An interrupt signal is generated whenever the failure status changes.

FEATUREs
► Part of the FlexRay™ electrical, physical layer
► Interface between communication controller and physical medium (twisted pair bus line)
► Support of data rates up to 10 Mbit/s
► Support of low power mode for an ECU
► Remote wake-up via bus line
► Enhanced diagnosis capability via SPI with interrupt generation
► Protection against overload damage by current limitation and overtemperature detection
► Bus driver outputs withstand - 27 V / + 40 V DC voltage
► Low EME due to balanced differential transmission

APPLICATIONs
► Transceiver in FlexRay™ nodes (ECUs)
