[1]
The TJA1028 combines the functionality of a LIN transceiver and a voltage regulator in a
single chip and offers wake-up by bus activity. The voltage regulator is designed to power
the Electronic Control Unit’s (ECU) microcontroller and its peripherals.
The LIN transceiver is the interface between a LIN master/slave protocol controller and
the physical bus in a LIN network. According to the Open System Interconnect (OSI)
model, these modules make up the LIN physical layer.

For enhanced thermal and electrical performance, the exposed center pad of the HVSON8 package should
be soldered to board ground (and not to any other voltage level).
