TJA1021TK/20/C,118 Description

Short technical summary and product information.

The TJA1021TK/20/C,118 from NXP Semiconductors is a LINbus transceiver, functioning as the interface between a LIN protocol controller and the physical bus. It is compliant with LIN 2.x, SAE J2602, and ISO 17987-4:2016 standards, making it suitable for automotive applications.

 

This transceiver supports baud rates up to 20 kBd and features optimized slew rate and wave shaping to minimize electromagnetic emission (EME). It offers high electromagnetic immunity (EMI) and passive behavior in an unpowered state. The device is designed for low power consumption, especially in Sleep mode, with wake-up recognition capabilities.

 

Key electrical characteristics include a wide supply voltage range of 5.5V to 27V and receiver hysteresis of 175 mV. The TJA1021TK/20/C,118 is available in an 8-HVSON (3x3 mm) package, suitable for surface mounting. It also provides protection mechanisms such as thermal protection and bus terminal short-circuit proofing.

 

This component is pin-to-pin compatible with TJA1020 and MC33662(B), offering design flexibility. Its features make it ideal for various in-vehicle sub-networks and other applications requiring robust LIN communication.
