Less is more – NXP shrinks LIN transceiver by 70% with the TJA1021


LIN Transceiver

NXP is giving car markers even more ways to deliver energy-efficient vehicles while keeping costs in check. The Product info on TJA1021TK TJA1021TK, the first LIN 2.1-certified transceiver, is now available in a space-saving HVSON8 package.


The HVSON8 is 70% smaller and lighter than a conventional SO8 package. Its compact size and light weight enables a smaller, more cost-effective module which helps reduce CO2 emissions. The HVSON8 package also offers significantly improved thermal resistance which enables high temperature applications. What’s more, the HVSON8 package uses a “dark green” molding compound that is free of Halogen and meets RoHS standard. As a result, the new package saves space while lowering its impact on the environment. The HVSON8 package has identical pin-out as the industry standard LIN transceiver in SO8, which eases the package adoption.


The NXP TJA1021TK transceiver features:


  • Excellent 6KV ESD performance according to IEC 61000-4-2 standard enables manufacturers to build electronic control units without incorporating external ESD protection.
  • Ultra low (10µA typical) sleep current, leakage current and low operation voltage contributes to reduced power consumption and less CO2 emission in the car.
  • Low operation voltage down to 5.5V that will make the device suitable for engine start related applications such as start/stop which can help to further reduce CO2 on the system level

With a transceiver portfolio of over 30 products, the broadest in the market, NXP supplies millions of transceivers to over a hundred direct customers every week. This broad customer base and high-volume production are the basis for a sustainable supply and ensure TJA1021TK customers will benefit from NXP's long-term commitment to increasing productivity and quality.


The Local Interconnect Network (LIN) protocol gives auto makers an inexpensive way to integrate sensors, actuators, and switches into the vehicle’s Controller Area Network (CAN) backbone. For several years, it's been the protocol of choice for a range of critical applications, including steering columns, door modules, mirror applications, roof modules, and more.
