Description

The low cost bus driver E910.55 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.

The device E910.55 supports normal and standby modes and provides remote wake up capability via bus line. The output (INH) can be used to control an external voltage regulator.
