FUNCTIONAL DESCRIPTION
The TJA1020 is the interface between the LIN master/slave protocol controller and the physical bus in a Local
Interconnect Network (LIN). The LIN transceiver is optimized for the maximum specified LIN transmission speed of
20 Kbaud providing optimum EMC performance due to wave shaping of the LIN output.
Operating modes
The TJA1020 provides two modes of normal operation, one intermediate mode and one very low power mode. Figure 3
shows the state diagram.
