The TJA1028T/3V3/10,11 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. TJA1028T/3V3/10,11 facilitates the development of compact nodes in Local Interconnect Network (LIN) bus systems. To support robust designs, the TJA1028T/3V3/10,11 offers strong ElectroStatic Discharge (ESD) performance and can withstand high voltages on the LIN bus. In order to minimize current consumption, the TJA1028T/3V3/10,11 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 TJA1028T/3V3/10,11 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.
