TJA1080
FlexRay transceiver
2.2 Low power management
I Low power management including two inhibit switches
I Very low current in Sleep and Standby mode
I Wake-up via wake-up symbol on the bus lines (remote), negative edge on pin WAKE
(local), and a positive edge on pin STBN if VIO is present
I Wake-up source recognition
I Automatic power-down (in Star-sleep mode) in star configuration
2.3 Diagnosis (detection and signalling)
I Overtemperature detection
I Short-circuit on bus lines
I VBAT power-on flag (first battery connection and cold start)
I Pin TXEN and pin BGE clamping
I Undervoltage detection on pins VBAT, VCC and VIO
I Wake source indication
2.4 Protections
I Bus pins protected against 8 kV HBM ESD pulses
I Bus pins protected against transients in automotive environment (ISO 7637 class C
compliant)
I Bus pins short-circuit proof to battery voltage (14 V and 42 V) and ground
I Fail-safe mode in case of an undervoltage on pins VBAT, VCC or VIO
I Passive behavior of bus lines in the event that transceiver is not powered
