LIN transceiver IC with on-chip voltage regulator in 3x3mm package

NXP Semiconductors has launched the new TJA1028, LIN transceiver IC family with an integrated low-drop voltage regulator in a 3x3mm leadless package. The voltage regulator is designed to power an automotive Electronic Control Unit (ECU), integrating the major peripheral functions around the microcontroller of a typical LIN-networked ECU into a single chip. TJA1028 is designed for use in LIN slave nodes in LIN bus systems such as rain-light sensors, mirror modules, window lifters and switch panels of cars.

NXP says it has designed these LIN devices specifically to meet the stringent requirements of vehicle OEMs, such as Volkswagen, Audi, Daimler, BMW, Ford, GM, Chrysler, and Renault supporting robust automotive designs.

The key features and specifications includes:

The TJA1028T/xxx/20 supports data communication speeds of 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.
The TJA1028 system basis chip (SBC) family can deliver up to 70 mA and is available in 3.3V and 5.0V variants.
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.
TJA1028 designed for Electrostatic Discharge (ESD) and Electromagnetic Compatibility (EMC) performance with bus output designed to withstand high voltages

"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."

Package: leadless HVSON8 package measuring 3x3mm. HVSON8 package features better thermal characteristics and improved heat dissipation compared to standard solutions, allowing the voltage regulator to deliver up to 70mA, which is 40 percent higher than the current industry standard, says NXP.
