LIN Mini System Basis Chip with integrated voltage regulator

The TJA1028 is a LIN 2.0/2.1/SAE J2602 and ISO 17987-4:2016 (12 V) compliant

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.
