NCV7383
FlexRay] Bus Driver
NCV7383 is a single −channel FlexRay bus driver compliant with
the FlexRay Electrical Physical Layer Specification Rev . 3.0.1,
capable of communicating at speeds of up to 10 Mbit/s. It provides
differential transmit and receive capability between a wired FlexRay
communication medium on one side and a protocol controller and
a host on the other side.
NCV7383 mode control functionality is optimized for nodes
without the need of extended power management provided by
transceivers with permanent connection to the car battery as is on
NCV7381. NCV7383 is primarily intended for nodes switched off by
ignition.
It of fers excellent Electromagnetic compatibility (EMC) and
Electrostatic discharge (ESD) performance.

supplied until V CC supply voltage is above uVCC_PORH
threshold (VCC > uVCC_PORH) − See Table 3.
Both supplies are monitored by under−voltage detectors
with individual thresholds and filtering times both for
under−voltage detection and recovery − see Table 15.
Junction Temperature Monitoring
In order to protect the NCV7383 from being damaged in
case of thermal event, a junction temperature monitoring is
implemented. High ambient temperature together with the
device high power dissipation can lead to junction
temperature reaching a critical temperature. Under certain
failure conditions (e.g. bus pin shorted to the supply voltage
during the transmitter active state), the device power
dissipation can be rapidly increased even though the
absolute short current is limited. If the junction temperature
is higher than TJSD (typically 165 °C) in Normal mode,
Thermal Shutdown flag is set and the transmitter is disabled.
This will reduce the power dissipation and decrease the
junction temperature.
The transmitter is enabled as soon as the Thermal
Shutdown flag is cleared. This requires the junction
temperature falling below the Thermal Shutdown level and
TxEN pin being set to High in Normal mode.
Logic Level Adaptation
Level shift input VIO is used to apply a reference voltage
uVDIG = uVIO to all digital inputs and outputs in order to
adapt the logical levels of NCV7383 to the host and/or the
FlexRay communication controller digital signal levels.
Internal Flags
The NCV7383 control logic uses a number of internal
flags (i.e. one −bit memories) reflecting important
conditions or events. T able 3 summarizes the individual
flags and the conditions that lead to a set or reset of the flags.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only . Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
