LIN 2.2A/SAE J2602 transceiver with TXD dominant timeout

7. Functional description

The TJA1029 is the interface between the LIN master/slave protocol controller and the

physical bus in a LIN network. According to the Open System Interconnect (OSI) model,

this interface makes up the LIN physical layer.

The LIN transceiver is optimized for, but not limited to, automotive applications with

excellent ElectroMagnetic Compatibility (EMC) performance.

7.1 LIN 2.x/SAE J2602 compliant

The TJA1029 is fully LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602 compliant. The

LIN physical layer is independent of higher OSI model layers (e.g. the LIN protocol).

Consequently, nodes containing a LIN 2.2A-compliant physical layer can be combined,

without restriction, with LIN physical layer nodes that comply with earlier revisions

(LIN 1.0, LIN 1.1, LIN 1.2, LIN 1.3, LIN 2.0, LIN 2.1 and LIN 2.2).

7.2 Operating modes

The TJA1029 supports modes for normal operation (Normal mode) and very-low-power

operation (Sleep mode). An intermediate wake-up mode between Sleep and Normal

modes is also supported (Standby mode). The state diagram is shown in Figure 3.
