The TJA1021T/10/CM 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 a LIN network. This transceiver is particularly suitable for automotive and industrial applications where a low-power and low-cost communication bus is essential.

Key Features

• Compatibility: Fully compatible with the LIN protocol specification 2.0, 2.1, and SAE J2602. It can also be used in ISO 17987-4:2016 compliant systems.
• Low Power Mode: Features a low-power sleep mode with a wake-up capability that helps in reducing the power consumption of applications when they are not active.
• High ESD Protection: Integrated Electrostatic discharge (ESD) protection exceeds ±8 kV according to IEC 61000-4-2, which ensures reliability and robustness under harsh conditions.
• Bus Pins Protection: The bus pins are protected against transients in the automotive environment, providing additional reliability for in-vehicle networks.
• Thermal Protection: Includes an overtemperature protection that disables the transmitter in case of excessive temperature, preventing damage to the device.
