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 TJA1028 is the interface between a LIN master/slave protocol controller and the
physical bus in a Local Interconnect Network (LIN). It is LIN 2.0/2.1/SAE J2602 compliant
and achieves optimum ElectroMagnetic Compatibility (EMC) performance by wave
shaping the LIN output.

HVSON8 package die supply ground is connected to both the GND pin and the exposed center pad. The
GND pin must be soldered to board ground. For enhanced thermal and electrical performance, it is
recommended that the exposed center pad also be soldered to board ground.
