TJA1029 - LIN 2.2A/SAE J2602 transceiver

General Description

The TJA1029 is the interface between the Local Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN network.

It is primarily intended for in-vehicle subnetworks using baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602.

Key Features

  • 2.1 General.
  • Compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602.
  • Baud rate up to 20 kBd.
  • Very low ElectroMagnetic Emissions (EME).
  • Very low current consumption in Sleep mode with remote LIN wake-up.
  • Input levels compatible with 3.3 V and 5 V devices.
  • Integrated termination resistor for LIN slave.

TJA1029 LIN 2.2A/SAE J2602 transceiver with TXD dominant timeout Rev. 2 — 24 April 2013 Product data sheet 1. General description The TJA1029 is the interface between the Local Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN network. It is primarily intended for in-vehicle subnetworks using baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602. The TJA1029 is pin-compatible with the TJA1020, TJA1021, TJA1022 and TJA1027. The protocol controller generates the transmit data stream. The TJA1029 converts the data stream into an optimized bus signal shaped to minimize ElectroMagnetic Emissions (EME). The LIN bus output pin is pulled HIGH via an internal termination resistor.
