Dual High-Speed CAN Transceiver with Standby Mode

TJA1059TK

The TJA1059 is a dual 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 and truck industries. It provides differential transmit and receive capabilities to (a microcontroller with) a CAN protocol controller.

The TJA1059 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 TJA1040. It offers improved Electro Magnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features:

  • Ideal passive behavior to the CAN-bus when the supply voltage is off
  • A very low-current Standby mode with bus wake-up capability on both channels
  • Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V
  • Complies with global OEM requirements, allowing a one-fits-all approach

The TJA1059 implements the CAN physical layer as defined in the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007). Pending the release of the updated version of ISO11898-2 including CAN FD, additional timing parameters defining loop delay symmetry are specified. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 2 Mbit/s.

These features make the TJA1059 an excellent choice for all types of HS-CAN networks containing more than one HS-CAN interface requiring a low-power mode with wake-up capability via the CAN-bus, especially for Body Control and Gateway units.
