TJA1028是一款LIN 2.0/2.1/SAE J2602收发器，带集成式低压差稳压器。稳压器可电流高达70 mA且提供3.3 V和5.0 V不同版本。
TJA1028便于开发本地互连网络(LIN)总线系统中的紧凑型节点。为支持可靠的设计，TJA1028提供强大的静电放电(ESD)性能且可在LIN总线上承受高电压。为了使电流消耗将至最低，TJA1028支持睡眠模式，在该模式中LIN收发器和稳压器电源关闭但同时仍具有通过LIN总线唤醒的能力。
TJA1028提供SO8封装，且还提供3 mm × 3 mm HVSON8封装使所需的板卡空间减少70%以上。此特点在板卡空间有限时极具价值。

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.
