General description

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 (up to 1 Mbit/s) CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1051 is a up from the TJA1050 high-speed CAN transceiver. 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

These features make the TJA1051 an excellent choice for all types of HS-CAN networks, in nodes that do not require a standby mode with wake-up capability via the bus.

Features

General

  • Fully ISO 11898-2 compliant
  • 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)

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
