FlexRay active star coupler

 Local wake-up via pin LWU

 Wake-up source recognition

 configurable per branch

 Enhanced supply voltage monitoring on VIO, VCC, VBUF and VBAT

 Auto I/O level adaptation to host controller supply voltage VIO

 Can be used in 14 V, 24 V and 48 V powered systems

 Enhanced bus error detection - detects short-circuit conditions on the bus

 Instant transmitter shut-down interface (BGE pin)

 Selective branch shut-down (partial networking)

2.3 Robustness

 Bus pins protected against 8 kV ESD pulses according to HBM and 6 kV ESD

pulses according to IEC61000-4-2

 All pins protected against 1000 V ESD according to CDM

 All pins protected against 200 V ESD according to MM

 No reverse currents from the digital input pins to VIO or VCC when the TJA1086 is not

powered up

 Bus pins short-circuit proof to battery voltage (14 V, 24 V or 48 V) and ground

 Overtemperature detection and protection

 Bus pins protected against transients in automotive environment (according to ISO

7637 class C)

2.4 Active star functional classes

 Active star - communication controller interface

 Active star - bus guardian interface

 Active star - voltage regulator control

 Active star - logic level adaptation

 Active star - host interface

 Active star - increased voltage amplitude transmitter
