Infineon TAE1453G: A High-Performance 3V CAN Transceiver for Automotive Applications

The evolution of automotive electronics demands robust and efficient communication networks. At the heart of these in-vehicle networks (IVNs), the Controller Area Network (CAN) bus remains a cornerstone technology. The Infineon TAE1453G emerges as a critical component, engineered to meet the stringent requirements of modern automotive designs. This high-performance 3V CAN transceiver is designed to provide a reliable communication link between a CAN protocol controller and the physical differential CAN bus.

A primary advantage of the TAE1453G is its operation from a single 3.0 V to 5.5 V supply. This low-voltage operation is essential for power-sensitive applications and aligns with the industry-wide shift towards lower core voltages in modern microcontrollers (MCUs). By eliminating the need for a separate 5V supply, it simplifies system design and helps reduce the overall bill of materials (BOM) and system cost.

Exceptional electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection are hallmarks of this device. It is engineered to withstand severe automotive environments, featuring high ESD robustness of up to ±8 kV (IEC 61000-4-2) on the bus pins. This ensures unparalleled reliability and longevity, safeguarding the network from transient disturbances common in automotive systems.

The transceiver offers low power consumption with advanced power management capabilities, including a stand-by mode with local and remote wake-up functionality. This is vital for supporting partial networking, where segments of the CAN network can be woken up on demand, significantly reducing the quiescent current and supporting the auto industry's goals for lower energy consumption and extended battery life.

Furthermore, the TAE1453G provides excellent electromagnetic emission (EME) performance, minimizing its radiated emissions and thus contributing to a lower total system EMC footprint. Its high immunity to electromagnetic interference (EMI) ensures error-free data transmission even in the presence of noise from motors, switches, and other electronic control units (ECUs).

Fully compliant with the ISO 11898-2:2016 standard, this transceiver is AEC-Q100 qualified, guaranteeing its reliability for automotive applications. It is ideally suited for body control modules, sensor and actuator networking, and other CAN-based systems requiring high data integrity and operational resilience.
