TJA1083TT: FlexRay node transceiver

The TJA1083 FlexRay node transceiver is compliant with the FlexRay Electrical Physical Layer specification V3.0.1. In order to meet JASPAR the equirements, it implements the ‘Increased voltage amplitude transmitter’ functional class. It is primarily intended for communication systems operating at between 2.5 Mbit/s and 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. The TJA1083 offers an optimized solution for Electronic Control Unit (ECU) applications that do not need enhanced power management and are typically switched by the ignition or activated by a dedicated wake-up line.

The TJA1083 provides a differential transmit capability to the network and a differential receive capability to the FlexRay controller. It offers excellent ElectroMagnetic Compatibility (EMC) performance as well as high ElectroStatic Discharge (ESD) protection.

The TJA1083 actively monitors system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring.

Outline 3d SOT402-1

  • Very low current consumption in Standby mode
  • Remote wake-up via a wake-up pattern or dedicated FlexRay data frames on the bus lines

  • Enhanced supply voltage monitoring for VCC and VIO
  • Two error diagnosis modes: Status register readout via the Serial Peripheral Interface (SPI) Simple error indication via pin ERRN
  • Overtemperature detection
  • Short-circuit detection on bus lines
  • Power-on flag
  • Clamping diagnosis for pins TXEN and BGE
  • Bus pins protected against ±6 kV ESD pulses according to IEC61000-4-2 and ±8 kV according to HBM
  • Bus pins protected against transients in automotive environment (according to ISO 7637 class C)
  • Bus pins short-circuit proof to battery voltage (14 V, 24 V and 48 V) and ground
  • Maximum differential voltage between pins BP or BM and any other pin of ±60 V
  • Bus lines remain passive when the transceiver is not powered
  • No reverse currents from the digital input pins to VIO or VCC when the transceiver is not powered

  • Bus driver - increased voltage amplitude transmitter
  • Bus driver - bus guardian control interface
  • Bus driver - logic level adaptation
  • Bus driver - remote wake-up
