TJA1044DTK/0J

Drivers, Receivers, Transceivers Overview

The TJA1044DTK/0J is a high-speed CAN transceiver from the Mantis family, designed for automotive applications. It interfaces between a CAN protocol controller and the physical two-wire bus. Operating with a supply voltage of 4.5 V to 5.5 V, it supports data rates up to 5 Mbit/s in CAN FD fast phase. The device features a very low-current standby mode with bus wake-up capability and excellent EMC performance without requiring a common mode choke. It is housed in an HVSON8 package.

Drivers, Receivers, Transceivers Feature Summary

• Fully compliant with ISO 11898-2:2024, SAE J2284-1 to SAE J2284-5, and SAE J1939-14 standards.
• Features ideal passive behavior to the CAN bus when the supply voltage is off.
• Includes a very low-current Standby mode with local and bus wake-up capability.
• Provides high ESD handling capability on bus pins (8 kV IEC and HBM).

Drivers, Receivers, Transceivers Applications

• High-speed CAN networks in automotive systems.
• Nodes requiring low-power modes with wake-up capability via the CAN bus.
• Applications optimized for 12 V automotive environments.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and pin configuration. Ensure compatibility with the target microcontroller's I/O voltage levels, particularly regarding the presence or absence of the VIO pin variant. Confirm that the component meets the required environmental and qualification standards for the intended application.

Drivers, Receivers, Transceivers Selection Notes

Select this variant if the design requires the HVSON8 leadless package for improved Automated Optical Inspection (AOI) capabilities. Consider the propagation delay characteristics when determining network topology size, as this variant may differ from others in the series. Verify that the system can support the specified standby undervoltage detection thresholds for reliable power management.

Drivers, Receivers, Transceivers Part Context

This component belongs to the NXP Semiconductors Mantis family of high-speed CAN transceivers. The family includes variants such as TJA1044T, TJA1044B, and TJA1044C, which offer different timing parameters and package options. The TJA1044 series represents an evolution over earlier generations like the TJA1040, offering enhanced EMC performance and lower power consumption.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same family include TJA1044GTK/3Z and TJA1044BTK/0J. These parts share similar functional characteristics but may differ in package dimensions or specific electrical timing parameters. Verify pinout compatibility and thermal requirements before substitution.
