TJA1052IT/5Y

The TJA1052IT/5Y Isolation Interface IC is a compact and versatile solution for CAN communication, seamlessly integrating isolator and transceiver functions into a single package to save board space. It complies with industry standards, supports high-speed data rates up to 5 Mbit/s, and ensures reliable performance with fewer components and guaranteed parameters. This IC offers robust electrical transient immunity, automotive-grade qualification, and compatibility with a wide voltage range. It also minimizes electromagnetic interference, is environmentally friendly, and is well-suited for modern automotive and industrial applications, making it a top choice for efficient and reliable CAN communication.

Safety: Isolation is required for safety reasons, eg. to protect humans from electric shock or to prevent the electronics being damaged by high voltages.

Signal integrity: The isolator uses proprietary capacitive isolation technology to transmit and receive CAN signals. This technology enables more reliable data communications in noisy environments, such as high-voltage battery management systems or the drive and regeneration systems in EVs and HEVs.

Performance: The transceiver is designed for high-speed CAN applications in the automotive industry, supplying the differential transmit and receive capability to a CAN protocol controller in a microcontroller. Integrating the galvanic isolation along with the transceiver in the TJA1052i removes the need for stand-alone isolation. It also improves reliability and system performance parameters such as loop delay

The TJA1052i belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features ideal passive behavior to the CAN bus when the transceiver supply voltage is off.

The TJA1052i implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.

The TJA1052i is an excellent choice for all types of automotive and industrial CAN networks where isolation is required for safety reasons or to enhance signal integrity in noisy environments.
