NXP Semiconductors N.V. (NASDAQ: NXPI) today announced theTJA1028, a LIN transceiver family with an integrated low-drop voltage regulator in a very small3x3mm leadless package. The voltage regulator is designed to power an automotive ElectronicControl Unit (ECU), integrating the major peripheral functions around the microcontroller of a typicalLIN-networked ECU into a single chip.
The combination of voltage regulator and bus transceivermakes it possible to develop compact yet powerful slave nodes in LIN bus systems. The TJA1028 isable to handle low-speed data communication in vehicles and is suitable for various LIN slaveapplications such as rain-light sensors, mirror modules, window lifters and switch panels.
Designed specifically to meet the stringent requirements of vehicle OEMs, such as Volkswagen,
Audi, Daimler, BMW, Ford, GM, Chrysler, and Renault, the TJA1028 offers strong Electrostatic
Discharge (ESD) and Electromagnetic Compatibility (EMC) performance with bus output designed to
withstand high voltages, enabling robust automotive designs.
The TJA1028 system basis chip (SBC) family can deliver up to 70 mA and is available in 3.3V and
5.0V variants. In order to minimize current consumption, the TJA1028 supports a sleep mode in
which the LIN transceiver and the voltage regulator are switched off while still having wake-up
capability via the LIN bus. The TJA1028 also offers a low-power standby mode, in which the LIN
transceiver is switched off while the voltage regulator is still supplying the microcontroller.
“With the TJA1028 family, NXP offers a compact, reliable and highly integrated solution which
enables engineers to design smaller LIN applications for the car without sacrificing functionality or
reliability,” said Rob Bouwer, product marketing manager, NXP Semiconductors. “As the number of
networked components in vehicles continues to increase, NXP offers solutions which ensure
automotive electronics communicate efficiently and intelligently. Through a scalable platform
approach, NXP’s SBC families make it easy to create robust, fail-safe ECUs quickly and easily.”
Compact 3x3mm PackageTo enable smaller, lighter and more environmentally friendly LIN2.1 modules, the TJA1028transceiver is available in a leadless HVSON8 package that measures only 3x3mm. Compared to anSO8 package, the HVSON8 reduces board space by up to 70 percent and enables smaller ECU sizes. The HVSON8 package features better thermal characteristics and improved heat dissipationcompared to standard solutions, allowing the voltage regulator to deliver up to 70mA , which is 40percent higher than the current industry standard.
The TJA1028T/xxx/20 ensures secure data communication up to 20 kBaud, the maximum specified
in the LIN standard. The TJA1028T/xxx/10 versions are optimized for a transmission speed of 10.4
kBaud, as specified in SAE J2602. By providing a flexible networking and power management
solution in a single small-sized package, the TJA1028 family provides full PCB design flexibility.
NXP and the LIN Bus
A recognized leader in in-vehicle networking (IVN), NXP Semiconductors is a key player in promotingthe Local Interconnect Network (LIN) bus as the industry standard for low-cost communications inautomotive applications. NXP offers a growing family of LIN2.x/SAE-J2602 compatible ICscomplementing its proven CAN portfolio – from stand-alone LIN transceivers and both generalpurposand application-specific LIN slaves, up to highly integrated CAN/LIN Fail-Safe System BasisChips (SBCs). As an associate member of the LIN consortium, NXP has steered the introduction of
LIN2.1/SAE-J2602 standard for in-vehicle sub-networks and has driven the definition of the LIN
physical layer.
