TCAN1043HG-Q1

The TCAN1043HG-Q1 is a high-reliability CAN transceiver designed for automotive applications, manufactured by Texas Instruments. It supports the Controller Area Network (CAN) physical layer according to ISO 11898-2 standards, enabling robust communication in electrically noisy environments typical of automotive systems. The device operates over a wide supply voltage range from 3.0 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems. This transceiver features advanced electrostatic discharge (ESD) protection, with ±6 kV HBM and ±6 kV CDM ratings, ensuring durability in harsh automotive conditions. It also includes integrated thermal shutdown and short-circuit protection, enhancing system reliability under fault conditions. The TCAN1043HG-Q1 supports data rates up to 1 Mbps, providing efficient and fast communication for real-time control applications such as engine management, body electronics, and infotainment systems. A key feature is its low quiescent current—typically just 1.7 mA in active mode and less than 1 μA in sleep mode—which contributes to energy efficiency and supports modern vehicle power management strategies. The device is qualified to AEC-Q100 Grade 1, ensuring long-term performance under extreme temperature ranges from -40°C to +125°C, suitable for under-hood and other demanding automotive environments. It is available in a compact, lead-free SOIC-8 package, facilitating easy integration into space-constrained designs. The TCAN1043HG-Q1 offers enhanced electromagnetic compatibility (EMC) performance through optimized signal integrity and reduced emissions, meeting stringent automotive EMC standards like CISPR 25. Its differential driver and receiver architecture ensures noise immunity and reliable data transmission even in high-noise environments such as those near motors or alternators. Designed for use in safety-critical systems, this transceiver supports fail-safe operation by maintaining defined logic levels during bus faults. Additionally, it includes an enable pin for flexible control of the transceiver’s operational state, allowing for seamless integration into microcontroller-based systems. With its combination of robustness, low power consumption, and compliance with automotive standards, the TCAN1043HG-Q1 is ideal for next-generation vehicle networks requiring high reliability, extended operating life, and minimal electromagnetic interference.
