1. General description

2. Features and benefits

The TJA1028 is a LIN 2.0/2.1/SAE J2602 transceiver with an integrated low-drop voltage

regulator. The voltage regulator can deliver up to 70 mA and is available in 3.3 V and

5.0 V variants. TJA1028 facilitates the development of compact nodes in Local

Interconnect Network (LIN) bus systems. To support robust designs, the TJA1028 offers

strong ElectroStatic Discharge (ESD) performance and can withstand high voltages on the

LIN bus. In order to minimize current consumption, the TJA1028 supports a Sleep mode

in which the LIN transceiver and the voltage regulator are powered down while still having

wake-up capability via the LIN bus.

The TJA1028 comes in an SO8 package, and also in a 3 mm  3 mm HVSON8 package

that reduces the required board space by over 70 %. This feature can prove extremely

valuable when board space is limited.
