TJA1081G
The TJA1081G is a high-performance CAN transceiver manufactured by NXP Semiconductors, designed for robust and reliable communication in automotive and industrial applications. It supports data rates up to 1 Mbps, making it suitable for high-speed CAN networks compliant with ISO 11898-2 standards. The device features low power consumption, with typical supply current of 3.5 mA in active mode and less than 1 µA in standby mode, enhancing energy efficiency in battery-powered systems.
This transceiver includes advanced protection mechanisms such as electrostatic discharge (ESD) protection up to ±40 kV (human body model), short-circuit protection for both the CANH and CANL lines, and overvoltage protection on the supply pins. These features ensure stable operation even under harsh electrical conditions commonly found in automotive environments.
The TJA1081G operates over a wide supply voltage range from 3.0 V to 5.5 V, enabling compatibility with various system architectures. It offers differential output drive capability, allowing it to interface directly with CAN controllers without requiring additional signal conditioning. Its integrated thermal shutdown feature prevents damage due to excessive temperature, further improving reliability.
Designed for use in demanding environments, the TJA1081G meets AEC-Q100 Grade 2 qualification, ensuring durability and performance in automotive applications. It supports both single and dual wire CAN configurations and provides excellent noise immunity through its high common-mode rejection ratio (CMRR). This makes it ideal for applications where electromagnetic interference (EMI) may be present, such as engine control units or chassis systems.
The transceiver is available in a compact 8-pin SO package, facilitating easy integration into space-constrained designs. It is widely used in vehicle networking systems including body control modules, infotainment systems, and telematics units. Additionally, it supports diagnostic functions that assist in fault detection and maintenance, contributing to improved system uptime and serviceability.
In industrial settings, the TJA1081G serves as a key component in factory automation, robotics, and process control systems where reliable real-time communication is critical. Its ability to operate across extended temperature ranges—from -40°C to +125°C—makes it suitable for both indoor and outdoor installations. Overall, the TJA1081G combines performance, safety, and flexibility to meet the evolving needs of modern electronic systems in automotive and industrial markets.
