About

Automotive CAN transceivers for scalable vehicle networks

Infineon's automotive CAN transceiver portfolio supports reliable communication across a broad range of in-vehicle network designs. The offering includes CAN FD transceivers up to 5 Mbit/s, CAN FD transceivers with partial networking, Endurance products for higher ambient temperatures and extended lifetime, and CAN FD SIC devices for data rates up to 8 Mbit/s. Designers can select bus wake-up, VIO, low-power modes, partial networking, dual-power-supply concepts, and DSO or TSON packages to match the ECU architecture and application requirements.

CAN FD performance with easier migration and lower system cost

Infineon's CAN FD 5 Mbit/s portfolio helps designers increase network bandwidth while minimizing redesign effort. Backward-compatible device families enable straightforward upgrades from previous CAN generations, protecting existing software and hardware investments. Excellent EMC performance can reduce the need for additional external components, helping lower BOM cost and PCB complexity. Flexible bus wake-up and power-management options support both switched and permanently powered ECUs, while low-power modes help reduce vehicle standby current and improve overall energy efficiency.

The portfolio includes the second-generation TLE9350Bx and TLE9351Bx families, available in multiple variants with or without VIO and bus wake-up functionality. These devices support migration from earlier 1 Mbit/s, 2 Mbit/s, and 5 Mbit/s CAN transceivers while maintaining familiar footprints and design concepts.

Dual power supply keeps CAN communication available during cranking

Battery cranking can temporarily reduce VBAT and disrupt communication in an ECU. The integrated dual-power-supply concept of the TLE9252x family allows the device to be supplied through VBAT, VCC, or both. If VCC remains within its functional range during battery cranking, the transceiver remains functional, helping the ECU maintain CAN communication. The concept also gives designers flexibility when defining the ECU power architecture.

TLE9252VSK and TLE9252VLC support CAN FD up to 5 Mbit/s, bus wake-up, sleep mode, and 3.3 V to 5 V VIO. They are available in PG-DSO-14 and PG-TSON-14 packages.

Endurance CAN FD for high-temperature and long-life applications

Future vehicle platforms increasingly require communication solutions that maintain reliable operation under demanding temperature and lifetime requirements. The Infineon Endurance CAN FD family helps engineers extend proven CAN FD architectures into harsh automotive environments while maintaining the same low-power operation, commun 

The TLT9251VLE, TLT9252VLC, and TLT9255WLC families bring Endurance capability to different CAN FD use cases, including bus wake-up, dual-power-supply architectures, and partial networking. Qualified as Infineon Grade 0+ Endurance devices, they support ambient temperatures up to 150°C and are designed for applications requiring increased robustness and extended operational lifetime.ication performance, and design flexibility available in the standard portfolio. This allows OEMs and Tier 1 suppliers to standardize designs across multiple application domains, reduce development complexity, and support long-term platform scalability.

Reduce vehicle power consumption with selective wake-up

Partial networking allows ECUs to remain in low-power mode until relevant CAN communication is detected. This significantly reduces unnecessary power consumption while maintaining network responsiveness. Infineon's CAN PN portfolio combines selective wake-up with very low sleep current, helping vehicle manufacturers improve energy efficiency and reduce CO₂ impact. Flexible placement options, high compatibility, and support for demanding automotive environments allow efficient implementation across distributed ECUs without increasing design complexity.

The TLE9255WSK, TLE9255WLC, and TLT9255WLC families integrate CAN FD communication with partial networking functionality. Endurance variants extend operation into demanding temperature and lifetime conditions while maintaining low-power performance.

Enable future vehicle networks with improved signal quality

As vehicle networks become larger and more complex, maintaining communication integrity becomes increasingly challenging. CAN FD SIC technology actively reduces signal ringing and improves signal quality, enabling robust communication at data rates up to 8 Mbit/s. Designers can support more nodes, larger network topologies, and future zonal architectures without major hardware changes. Pin-compatible upgrades, higher network robustness, and improved EMC behavior help accelerate adoption while reducing validation effort and supporting future vehicle communication requirements.

The TLE9371x CAN FD SIC family is available with or without VIO support and provides pin-compatible migration from conventional CAN FD transceivers. The family combines bus wake-up capability with Signal Improvement Capability (SIC), enabling reliable high-speed communication in increasingly complex automotive networks.
