TCAN3403-Q1

The TCAN3403-Q1 is a high-reliability CAN transceiver designed for automotive applications, manufactured by Texas Instruments. It supports the Controller Area Network (CAN) physical layer as defined by ISO 11898-2 and operates with a supply voltage range of 3.0 V to 5.5 V, making it suitable for both 3.3 V and 5 V systems. The device features robust electrostatic discharge (ESD) protection up to ±8 kV HBM, ensuring resilience in harsh automotive environments. This transceiver offers a high data rate capability of up to 1 Mbps, enabling efficient communication in modern vehicle networks. Its low quiescent current—typically 1.6 mA in active mode and less than 1 µA in sleep mode—enhances power efficiency, which is critical for battery-powered or energy-conscious systems. The TCAN3403-Q1 includes integrated diagnostics such as open-wire detection, short-to-battery/ground protection, and fault reporting, allowing for improved system reliability and simplified troubleshooting. Designed for compliance with AEC-Q100 Grade 1 qualification, the TCAN3403-Q1 is built to withstand extreme temperature ranges from -40°C to +125°C, making it ideal for engine bay and chassis applications. It also supports flexible node configurations through its enable pin and sleep control, enabling seamless integration into complex vehicle architectures. The device’s differential output stage ensures strong noise immunity, while its wide common-mode voltage range improves signal integrity in electrically noisy environments. Common applications include body control modules, powertrain systems, infotainment units, and advanced driver-assistance systems (ADAS). Its compatibility with standard CAN protocols and support for multiple network topologies make it a versatile choice for engineers designing next-generation automotive electronics. The TCAN3403-Q1 is available in a compact, lead-free SOIC package, facilitating high-density board layouts without compromising performance or thermal management.
