High-Speed CAN Transceiver - Mantis Family

TJA1057

Roll over image to zoom in

The TJA1057 is part of the Mantis family of high-speed CAN transceivers. It provides an interface between a controller area network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1057 offers a feature set optimized for 12 V automotive applications, with significant improvements over first- and second-generation CAN transceivers from NXP, such as the TJA1050, and excellent electro magnetic compatibility (EMC) performance.

The TJA1057 also displays ideal passive behavior to the CAN bus when the supply voltage is off.

Features

General Features

  • Fully ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant
  • Optimized for use in 12 V automotive systems
  • Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI), according to proposed EMC Standards IEC 62228-3 and SAE J2962-2
  • AEC-Q100 qualified
  • Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
  • Shorter propagation delay on the TJA1057B and TJA1057C variants supports larger network topologies
  • Variants with a VIO pin allow for direct interfacing with 3.3 V to 5 V microcontrollers. Variants without a VIO pin can interface with 3.3 V and 5 V-supplied microcontrollers, provided the microcontroller I/Os are 5 V tolerant.

Predictable and Fail-safe Behavior

  • Functional behavior predictable under all supply conditions
  • Transceiver disengages from bus when not powered (zero load)
  • Transmit Data (TXD) dominant time-out function
  • Internal biasing of TXD and S input pins

Protection

  • High ESD handling capability on the bus pins (8 kV IEC and HBM)
  • Bus pins protected against transients in automotive environments
  • Undervoltage detection on pins VCC and VIO
  • Thermally protected

TJA1057GT(/3)/TJA1057GTK(/3)

  • Timing guaranteed for data rates up to 5 Mbit/s
  • Improved TXD to RXD propagation delay of 210 ns
