Description

TJA1044GTKZ

Overview

The TJA1044GTKZ is a high-performance transceiver designed for automotive applications, specifically for Controller Area Network (CAN) bus systems. This device is tailored to provide reliable and robust communication in harsh environments, making it suitable for a wide range of vehicle systems and networks.

Key Features

• High-Speed CAN Transceiver: Supports data rates up to 1 Mbit/s, making it suitable for high-speed CAN applications.
• Compliant with ISO 11898-2: Meets the international standard for high-speed CAN, ensuring compatibility and interoperability with other CAN devices.
• Advanced Receiver: Offers excellent receiver performance, including high input impedance and low input current, which minimizes the load on the CAN bus.
• Transmit Data (TXD) Dominant Time-out: Automatically switches the transmitter to recessive state if a dominant state on TXD is longer than the dominant time-out, preventing bus lockup.
• Bus Fault Protection: Provides protection against short circuits to positive and negative battery voltage, and to ground, enhancing the reliability and safety of the CAN bus system.
• Thermal Shutdown: Protects the device against overheating, ensuring safe operation even under extreme conditions.
• SPLIT Output: Offers a split output to the CANH and CANL lines, reducing electromagnetic emission (EME) and improving the signal-to-noise ratio.
• Available in SO8 Package: Compact packaging suitable for space-sensitive automotive applications.

Applications

• Automotive Networks: Suitable for CAN-based systems in vehicles, including engine control units, body control modules, and advanced driver-assistance systems (ADAS).
• Industrial Control Systems: Can be used in industrial automation and control applications where a reliable, high-speed CAN bus is required.
• Medical and Aerospace: Applicable in medical devices and aerospace systems where rugged and reliable communication is critical.
