TCAN1473-Q1

The TCAN1473-Q1 is a high-reliability, CAN transceiver designed by Texas Instruments for automotive applications. It supports the Controller Area Network (CAN) physical layer with a data rate up to 1 Mbps, ensuring robust communication in electrically noisy environments typical of modern vehicles. The device operates across a wide supply voltage range of 3.0 V to 5.5 V, making it compatible with various vehicle power systems. This transceiver features enhanced electromagnetic compatibility (EMC) performance and integrated protection mechanisms, including overvoltage, electrostatic discharge (ESD), and short-circuit protection. These protections meet stringent automotive standards such as ISO 11452-2 and ISO 10605, ensuring reliable operation under harsh conditions. Its low quiescent current draw enhances system efficiency, particularly important in battery-powered or energy-conscious automotive designs. The TCAN1473-Q1 supports both classic CAN and CAN FD (Flexible Data-Rate) protocols, enabling higher data rates up to 5 Mbps in the data phase while maintaining backward compatibility with legacy systems. This flexibility makes it ideal for evolving vehicle architectures that require increased bandwidth for advanced driver-assistance systems (ADAS), infotainment, and powertrain control modules. It includes a sleep mode with a wake-up feature triggered by bus activity, minimizing power consumption during idle states—critical for meeting automotive power management requirements like those defined in the OBD-II standard. The device also offers configurable slew rate control, which reduces electromagnetic emissions and improves signal integrity on long cables or high-speed networks. Designed for use in safety-critical automotive systems, the TCAN1473-Q1 complies with AEC-Q100 Grade 1 qualification, guaranteeing operation from –40°C to +125°C. Its robust packaging options, including a 16-pin SOIC package, support easy integration into existing PCB layouts without requiring significant design changes. Applications include body control modules, gateway ECUs, telematics units, ADAS sensors, and battery management systems where reliable, high-speed communication is essential. The transceiver’s ability to operate reliably in extreme temperatures, combined with its low-power and high-EMC performance, positions it as a preferred choice for next-generation automotive electronics.
