High-Speed CAN Transceiver

TJA1051

The TJA1051 is a high-speed CAN transceiver that 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 differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1051 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features:

  • Ideal passive behavior to the CAN bus when the supply voltage is off
  • TJA1051T/3 and TJA1051TK/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V

Features

General Features

  • Fully ISO 11898-2:2003 compliant
  • Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
  • Suitable for 12 V and 24 V systems
  • Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
  • VIO input on TJA1051T/3 and TJA1051TK/3 allows for direct interfacing with 3 V to 5 V microcontrollers (available in SO8 and very small HVSON8 packages respectively)
  • EN input on TJA1051T/E allows the microcontroller to switch the transceiver to a very low-current Off mode
  • Available in SO8 package or leadless HVSON8 package (3.0 mm × 3.0 mm) with improved Automated Optical Inspection (AOI) capability
  • Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
  • AEC-Q100 qualified

Low-power Management

  • Functional behavior predictable under all supply conditions
  • Transceiver disengages from the bus when not powered up (zero load)

Protection

  • High ElectroStatic Discharge (ESD) handling capability on the bus pins
  • Bus pins protected against transients in automotive environments
  • Transmit Data (TXD) dominant time-out function
  • Undervoltage detection on pins VCC and VIO
  • Thermally protected
