Brief Functional Description
The low cost bus driver is a part of the electrical, phy-
sical layer in a FlexRay communication network. The
E
910.55
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 informati-
on concerning failure detection on the bus lines (e.g.
short-circuits, ground loss) and overtemperature con-
dition. An interrupt signal is generated whenever the
failure status changes.
The device supports normal and standby modes and
provides remote wake up capability via bus line. The
output (INH) can be used to control an external vol-
tage regulator.
