The TJA1028TK/3V3/20 is a high-performance LIN (Local Interconnect Network) transceiver designed by NXP Semiconductors, which provides a robust interface between the LIN master/slave protocol controller and the physical bus in automotive and industrial applications. This transceiver is particularly suitable for nodes in LIN bus systems according to the LIN 2.x, SAE J2602, and ISO 17987-4 standards.

The device integrates a voltage regulator with a 3.3V output, which can supply up to 20mA to external components, such as a microcontroller. This feature simplifies system design by reducing the need for an additional voltage regulator. The TJA1028TK/3V3/20 supports a wide operating voltage range and is protected against battery voltage drops, making it highly resilient in the challenging automotive environment.

• Key Features:
• Integrated 3.3V voltage regulator capable of supplying 20mA
• Compatible with LIN protocol specification 2.x, SAE J2602, and ISO 17987-4
• Low power consumption in sleep mode, contributing to energy savings
• Robust Electrostatic Discharge (ESD) protection
• High immunity to electromagnetic interference (EMI)
• Thermal protection with an overtemperature shutdown feature
• Wide operating supply voltage range from 5V to 27V

The TJA1028TK/3V3/20 is designed with an emphasis on low-power operation, featuring a sleep mode that significantly reduces the current consumption when the LIN bus is inactive. This makes it an excellent choice for battery-operated and energy-sensitive systems. The device also includes a wake-up function via the LIN bus or an external trigger, allowing for remote activation of LIN nodes.

The robust design of the TJA1028TK/3V3/20 ensures reliable communication in the presence of high electromagnetic interferences, which is common in automotive environments. Additionally, the device's ESD protection exceeds automotive requirements, thereby providing a high level of reliability and longevity for the end product. Its overtemperature shutdown feature safeguards the device and the system from thermal damage under extreme conditions.

Overall, the NXP TJA1028TK/3V3/20 LIN transceiver is an excellent choice for designers looking for a reliable, low-power, and easy-to-integrate solution for LIN-based communication systems.
